Hi, This Might have nothing to do with your problem, but you have nothing to loose by the sounds of it, the breather pipe from the bottom of the sump (behind the starter motor) to the top of the rocker box, mine was clogged up with slug like greese causing sencer problems and giving false information to the computer. (running rought) you got nothink to loose, try it.

Hi. I can give you a simple, but time consuming test to do to check your intermittent compression problem. New hydraulic lifters cause a lot of problems until its settled. Remove the camshafts and the hydraulic lifters. Take each hydraulic lifter and put it in a vice(becarefull not to damage them) and squeeze out all the oil in the lifters. Then put them back and replace camshaft and allign timing marks. Check compression ratio. What happens sometimes is that the oil pressure is too high(stuck oil pressure release valve or cold thick oil) and this causes the oil pressure to put so much pressure on the hydraulic lifters, that it slightly forces the valve open. That will cause your low compression as well as backfire through the intake.

Testimonial: "I have "bled" the lifters and replaced them now there is,not sure if there is enough, compression and my fuel pump is acting funny. When you place the key in and turn it the pump kicks in as normal, when you turn the key and the car cranks the pump sounds if it restarts, now I think the car is struggling with feul"

My head gasket blew out so i did that and it never turned back on so i did the timing chain and nothing so i put fuel filter nothing new plugs and still get it what else could or be


Year make and model ?
It takes spark, fuel, and compression at the right time for an engine to run. So you are probably missing one or more of these three things.
Have you checked compression on all cylinders ? Is the cam timing correct ? Do you have fuel and spark ?

Have 1996 C1500 vortex 4.3 blowed head gaskets ,replaced head gasket but #4 cylinder is misfiring & only has 30psi & 60psi #3 possible burt valve,burnt piston,compression ring damaged or?


the first thing is --did you do anything with the head ( machined flat-checked for cracks)
did you run a thread tap down the stud holes and blow out any oil,water in the holes
did you inspect the valve heads to see for burnt heads
Why did you replace the head gasket to start with
Low pressure between adjacent pistons indicates blown gasket between those cylinders
to do a head job properly, remove the head and check for warps and cracks ( head machined flat) clean out the threads of the studs and blow any thing out of the holes
next check that all the head studs are the same length and insert each stud in the head so that all the studs sit the same distance above the head before tightening down
next tighten down using the correct tightening sequence so that the gasket is evenly compressed
tighten down to the correct tension or degrees of turn as is stated in the specifications
any piston or valve or ring damage would be restricted to the one piston and would not show up in adjacent cylinder

What would make a 1995 ford ranger not idle after replacing head gasket


Best have it checked by a garage. You replaced head gasket was the timing put back absolutely correctly?
Have you checked the engine compression?
Did you check the head for warping / air tightness?
Were all the ancilaies replaced correctly?
There could be anything causing the problem

My 1994 corolla 1.3 carburetor does not run smooth when i drive it from a stop. i have to press more gas and still the engines somewhat shivers.


There are two possible problems affecting your car. The first is the head gasket. The second is the timing chain. Each can make your Corolla perform as you describe it.

There is one way to find out quickly if the engine involves the head gasket, or not. That way is a compression test. This test does require some specialized equipment and knowledge. It is best to leave it to a trained technician.

When the test is run, the ignition removes the spark plug from the block and inserts the testing device. The compression of each cylinder is measure in this way. If the reading that results is too low on two cylinders, it is very likely that your car's problem is the head gasket. When a head gasket blows out, a weakened piece of the head gasket fails, leaving a rather large vacant space behind. This compromises the engine's sealing and its vacuum balance. Two cylinders are affected by the gasket failure and their compression tests will show low, but not failed compression. Your Corolla will perform just as you describe it.

If you have the compression test performed and it shows the compression on all four cylinders is correct. Then it is time to replace the timing chain.

How can I fix the head gasket


The gasket replacement task is similar for most petrol-engined cars. It is a fairly straightforward task for a mechanic or someone with very good mechanical skills. However it is a task full of pit-falls for a novice mechanic and if you are determined to do it yourself and it is the first headgasket you have tried to replace, then you should get hold of the workshop manual covering that particular engine and follow it carefully.

You will in general need to disconnect everything attached to the head, so that you can lift it clear. That will include the timing chain or belt, fuel lines, water lines, hoses, electrical, manifolds, etc., as well as unscrewing the head bolts in the correct rotational sequence. There are specific and detailed procedures that must be followed in order to correctly put all these components back - especially in regard to using a torque wrench to correctly tighten and re-tighten the head, and in regard to re-timing the camshaft to obtain the correct valve timing and setting up the tensioner.

With the head removed you will need to get the head checked for flatness as only a few thou of warp will defeat your attempts to get a good seal on the new gasket.

It may also pay to get the head checked for microscopic cracks. [This is more applicable for CI heads.]

I would also take the opportunity to de-coke the head and pistons and examine the bores for wear and scoring. If the engine has been run for long with the gasket leaking water to any cylinder, then that bore is likely to be damaged / worn and without further repair you may find compression is down on that cylinder after head replacement.

The ONLY substitute for experience is a good brain and the ability to understand and follow a detailed manual exactly. If in doubt along the way, stop and ask.


After reading this you may decide it is beyond you and better to employ an experienced mechanic. Your call.

Cheers

1992 ford explorer there's water in oil so have a cracked head or blown head gasket after its replaced how do I reset the compression and do I need to reset eec


When you get the new head gasket on and the new head (if needed) back together, and your timing from the timing belt or chain is correct, the compression should be good. There is no resetting of compression.
On a '92, you should not need to worry about resetting the eec. That is for newer vehicles.

My 93 excel seems to be leaking pressure between cld 1&2 there is almost no pressure in these 2 wheras 3&4 has 175 psi in each which seems high. no external leaks, no water loss. only had car for...


The 175psi is not high for cylinder compression (I believe I interpreted it correctly). Two adjacent cylinders with low compression almost always means the head gasket has blown the fire ring between the cylinders. Pull the head, have it checked and or milled. New head gasket set, timing belt, oil change and get her going.

What would cause my1999 Saturn sl1 not to start after a new head gasket was put on? Ok so today we replaced the head gasket on my 1999 Saturn Sl1 single cam. We made sure the timing chain was put back on...


Check the cam/crank sensors. Also, if the car happens to have a distributor, make sure it is not 180 degrees off. If this does not help, then do a compression check. Remember, and engine only needs three things to run. Fuel, Spark, and Compression. (in order of course.) The firing order for your engine is 1,4,3,2.
