How to find engine size

If you have a stock engine that should be relatively easy. Also if you have a stock 2005 FLSTC you would have a Twin cam 88 with a displacement of 88 cubic in. or 1450 cc

Cam bearings

Remove the rocker cover to ascertain the damage done . It may not be bearings but seized valve in the head. To fix cam bearings properly it may necessitate the head removal and machining both the head surface and then the bearings should be line bored to realign the cam shaft correctly. Some Nissan products have the cam bearing housings adjustable with shims to align the holes correctly and if not done will break the cam shaft. IT may be the cam shaft is broken and jammed . What ever it will not be just a case of putting in new bearings until you have the head and bearing alignment checked out by an engineering shop.

Engine tap

I have had a few suzuki's and they are great little engines provided they get serviced on a regular basis, as they are a bit sensitive on the cylinder heads as the cam bearings are a fixed part of the head.This is a bit of a problem when you get metal wear that gets into the oil and gets in between the cam and cam bearings which are only Aluminium, thus the iron filings in the oil will scour the aluminium cam bearings being softer than steel or metal so to speak. So the good thing to do is make sure that the oil is always clean and free from metal wear deposits, and the only way to prevent this is to do an oil change at least every 10,000 miles or 20,000 kilometres, although every 5,000 miles or 10,000 kilometres is best, failing which you will get a tapping sound in the engine head which means that the bearings have been scoured or maybe if you're lucky it might just only be the incorrect valve clearance settings.Other than that I have never known them to give other engine problems out of proper maintained use.They are extremely reliable. I suggest you remove the tappert cover and remove the cam shafts to check whether the camshaft bearings are not scoured. Best of luck.

Engine knocking

First check this information about "engine noses"...
A clicking or tapping noise that gets louder when you rev the engine is probably "tappet" or upper valvetrain noise caused by one of several things: low oil pressure, excessive valve lash, or worn or damaged parts.

First, check the engine dipstick to see if the oil level is low. If low, add oil to bring it back up to the full mark. Is the engine still noisy? Check your oil pressure. A low gauge reading (or oil warning light) would indicate a serious internal engine problem that is preventing normal oil pressure from reaching the upper valvetrain components. The cause might be a worn or damaged oil pump, a clogged oil pump pickup screen or a plugged up oil filter. Using too thick a viscosity of motor oil during cold weather can also slow down the flow of oil to the upper valvetrain, causing noise and wear.

Worn, leaky or dirty lifters can also cause valvetrain noise. If oil delivery is restricted to the lifters (plugged oil galley or low oil pressure), the lifters won't "pump up" to take up the normal slack in the valvetrain. A "collapsed" lifter will then allow excessive valve lash and noise.

If you can rule out lubrication-related problems as a cause, the next step would be to remove the valve cover(s) and check valve lash. On older import engines, mechanical lifters require periodic valve lash adjustments (typically every 30,000 miles). Too much space between the tips of the rocker arms and valve stems can make the valvetrain noisy -- and possibly cause accelerated wear of both parts.

To measure (and adjust) valve lash, you need a feeler gauge. The gauge is slid between the tip of the valve stem and rocker arm (or the cam follower or the cam itself on overhead cam engines) when the piston is at top dead center (valve fully closed). Refer to a manual for the specified lash and adjustment procedure. Also, note whether the lash spec is for a hot or cold engine (this makes a big difference!).

On engines with hydraulic lifters, oil pressure pumps up the lifters when the engine is running to maintain zero lash in the valvetrain. This results in quiet operation. So if the rocker arms are clattering, it tells you something is amiss (bad lifter or worn or damaged parts) or the rocker arms need adjusting.

Inspect the valvetrain components. Excessive wear on the ends of the rocker arms, cam followers (overhead cam engines) and/or valve stems can open up the valve lash and cause noise. So too can a bent pushrod or a broken valve spring.

Usually bad news. A deep rapping noise from the engine is usually "rod knock," a condition brought on by extreme bearing wear or damage. If the rod bearings are worn or loose enough to make a dull, hammering noise, you're driving on borrowed time. Sooner or later one of the bearings will fail, and when it does one of two things will happen: the bearing will seize and lock up the engine, or it will attempt to seize and break a rod. Either way your engine will suffer major damage and have to be rebuilt or replaced.

Bearing noise is not unusual in high mileage engines as well as those that have been neglected and have not had the oil and filter changed regularly. It can also be caused by low oil pressure, using too light a viscosity oil, oil breakdown, dirty oil or dirt in the crankcase, excessive blowby from worn rings and/or cylinders (gasoline dilutes and thins the oil), incorrect engine assembly (bearings too loose), loose or broken connecting rod bolts, or abusive driving.

Bearing wear can be checked by dropping the oil pan and inspecting the rod and main bearings. If the bearings are badly worn, damaged or loose, replacing the bearings may buy you some time. But if the bearings are badly worn or damaged, the crankshaft will probably have to be resurfaced - which means a complete engine overhaul or replacing the engine is the vehicle is worth the expense.

The cause here may be Spark Knock (Detonation) caused by an inoperative EGR valve, overadvanced ignition timing, engine overheating, carbon buildup in the combustion chambers, or low octane fuel.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Sluggish oil pressure

To start with, why on earth would an engine with re-used bearings, oil pump and cam need a "break-in" in the first place?

Then, it deserves mention that the number 1 cause of low oil pressure in a small block chevy engine is wear in the cam and/or cam bearings. The second highest cause is worn crankshaft main and rod bearings and the third highest cause is an oil pump that has too much internal clearance or an oil pump pick-up screen that is clogged with debris from shady repair work.

Sounds to me like you problem is probably related to the fact that the engine has not been "built", but rather, assembled with the same old worn out parts that most likely caused the need for it to be "built" in the first place.

1991 engine gearcase blueprint specs to machine new cam bearimg hole

It depends on what engine you're talking about. I've been messing with Harley's since 1966 and I've NEVER seen a blueprint drawing of an engine casting. Now, all may not be lost. It depends on whether the engine is a Big Twin or Sportster. Various companies make plates that are designed to **** bushings or hone outer races of bearings for the camshafts. Maybe one of these plates can be used to obtain the original position of the cam bearing hole. Usually, the cam bearing holes have a place around them that is machined that is centered on the same center that the original cam bearing hole was centered on.

Is there a known problem with oil pump on 88' S in 2000

Well, it depends. There was indeed a known problem with the cam bearing plate and that's what the oil pump is mounted on. Seems H-D used roller bearings instead of needle bearings on the cams and the bearing were failing. It was something like that anyway. Harley would not fix them under warranty until they failed. Instead, they lengthened the warranty out to 50,000 miles on the bearings. Whether or not this has anything to do with an oil pump problem, I don't know. You didn't say why you thought you had an oil pump problem.

Good Luck

Growling engine noise only at idle. Cam area

Take all of the belts off for a short run at idle. If the sound goes away it is pulley related, spin each pulley and listen for bearing noise, also check for play at this time.

If the noise does not go away when the motor is driving no accessories you have a more serious problem.

We are replacing the right hand cam of a audi allroad 2.5 diesel so we need to the timing marks for the camshaft befor we put the new cam in

You need to Replace both cams on this engine not just one. With uneven wear you will not get the same life out of the two cams and it will damage the engine. so replace both cams. First pull #1 cylinder plug be sure both valves are closed fully and is on compression stroke and the crank at TDC top dead center, put a piece of plastic into #1 cylinder to make sure it is all the way up. Once you have determined that it is note the position of the cam marks normally they are at 12 o'clock straight up on both cams with the crank at 0 degrees then install both cams. Again Replace both, However you need to check the cam bearings, to do that use a small mag light and shine down the bore of the cam shaft if you see copper color in the cam bearing holes you will need to replace the cam bearings or you will not have oil pressure and will damage the engine and will have wasted your money. you can Rent a cam bearing removal and installation tool and if you remove the radiator you should be able to replace them, you may have to remove the motor mounts and jack up the engine to clear the cam holes to replace the bearings. I can't stress enough how important it is to check the bearings and change both cams. I thought it my responcibilty to tell you this even if it was locked to another expert. Good luck.
