Engine head gasket

I suggest you purchase a repair manual for your Benz, if available. It's a major task to remove the head(s) and replace the gasket. You'll need torque sequencing specs, probably new head bolts, etc. You should have the head checked at a machine shop for warping. I think it's beyond the scope of this web site to give very detailed and explicit instructions for such a major engine job. Good luck....

In my 1980 Pontiac Lehmans there's a hesitation between gears and a minor transmission leak can I have some ideas also there is ticking under the valve cover

The first symptom on your Lemans can be a vacumn leak...check ALL rubber hoses, and the EGR valve hose for cracks, and replace as needed...a vacumn leak or imbalance can also alter the tranny shift points:(... Unfortunately the ticking under the valve cover sounds like a sticky lifter...You can try to lubricate this by changing oil...but use one quart of GM tranny fluid in place of one quart of oil...run motor for ONE day only, and then change oil again with the correct viscosity...10W30 I like Valvoline High Mileage:) Hope these inexpensive fixes work for your classic Lemans!!

Dented oil pan on 1980 AMC Concorde, how is best way to repair?

oil pan will need to be removed.a small dent could be hammered out from inside,if its cracked,welding is a possibility,but care must be given to maintain correct alignment at gasket surface to avoid leaks.
a replacement pan might be available after-market,or from an auto recycler [junkyard] .specifics of engine displacement & application will be required to order matching part.

Oil leak at the bottom of the oil pan. Still leaking after i tightend the pan bolt. What should i check next, can this cause other problems?

Dear Sir,
Here is the oil leaking Problem Identifying Technique

Engine oil leaks from the valve cover gasket are common.

The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.

External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.

Engine oil leaks at the distributor can be misdiagnosed as leaks from the intake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.

If the oil filter casing shows signs of distortion from excessive oil pressure, the oil pump should be replaced.

Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.

Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

I think it helps to analyse u r Problem

Newer oil pan gaskets for Ford, not like original..leaking again

try warming up the engine a little then re-tightening the bolts,if that doesnt work,mark where its leaking and pull the pan back off and apply sealant to that area a little heavier than the rest of the gasket surface,dont use too much on a new gasket,just a really thin coat...USE "ULTRA BLUE" sealant,NOT blue or black RTV silicone,silicone wears out and it can leak after a while..Allow the ultra blue sealant to dry for about 30 minutes before re-assembling it,and clean off all oil from the gasket before applying the sealant,its ok to apply it to both sides of the gasket,and add a glob to all 4 corners where the gasket meets with rubber seals around the crankshaft,but put those globs on right before you put the pan back in place,the sealant has to be wet to squish in enough..i hope this helps

2004 Chevy Cavalier Oil leak

Replacing an oil pan gasket on a car shouldn't be too difficult for you, say, about an hour or two. As long as you follow some simple guidelines, the leak should be eliminated. Improper tightening or seating of the gasket material can defeat the purpose of your work. Grab a Haynes manual, or a tech guide for your vehicle, and have it handy.

I would suggest tracking the oil leak to ensure that it's not your front seal on your crankshaft. The amount of oil that you describe sounds like a bit much for an undisturbed oil pan gasket.

Need torque specs for oil pan gasket

There likely is a spec for oil pan but unless you are a finatic, you really don't need to know what it is. Simple rule: Don't crank down ******* any fastener. If corners near crank ends have larger fasteners, you can tighten them a bit more than on siderails. Before tightening anything, install all bolts finger tight, to ensure that they are not cross threaded. To avoid warping pan, tighten from the center of the pan, working towards both ends, alternating from side to side as you go. When you are finished, go over it again, using the same amount of force on each bolt. As I said, end bolts can if larger in diameter, be tightened more but be careful not to tighten so much that you will either split or push the gasket out the sides.. Anywhere two gasket ends **** together, I recommend using a sensor -safe dab of silicone. An oil pan is not under any mechanical stress or pressure. I have used this method for many years and NEVER had one leak. If you really need #s, small fasteners get about 12-15in lbs, larger ones about 20.

Leaking oil pan gasket

Check the pan to make sure it is not cracked or warped. Also notice where most of the leak is coming from. When you took off the old gasket, did you scrape off all of the old material? If you used a screwdriver to do that, you may have nicked the metal and created a path for oil to leak. If you didn't scrape off the old material and any RTV sealant, you will want to, using a plastic scraper. There are sprays that dissolve this material too if it is too hard to scrape off.

If that area is nicked badly and you haven't used RTV sealant, you may want to put a small amount all over the area that the gasket will cover, not just the nicked area but the whole area that the pan gasket will cover- it doesn't take much and if you smear too much on, it will just ooze out and make things messy - just a fine coating will do.

As you tighten up the bolts, make sure you tighten in an alternating pattern as they begin to contact the gasket and get tight so a bolt on one side get fastened down as often as one on the other side gets fastened to avoid warping the pan.

Hope this helps.

Clean the area well with gas or a spray cleaner/degreaser where you know it's leaking from. Since you don't want to go through the proper repair by removing the oil pan to replace the gasket, do this instead. After the area is clean and dry, tighten all the oil pan bolts first. Then get a tube of black RTV and put some on the end of your finger that reaches the spot the best and push the RTV into the area between the oil pan, gasket, and block. Make sure it's well covered to plug the leaky gasket and let the RTV cure. Shortly, your leak ahs been stopped. I personally do this myself to stop that same leak on my Chevy 383 I put in my Motor Home so I don't have to drop the pan. And it works.

Drain the oil and remove the oil pan. Make sure the two gasket surfaces are mirror clean. Take a very close look at the gasket surface on the engine and the gasket surface on the oil pan. Look for ANY signs of damage. Get the pan and engine as clean as you can get it so you can see more clearly if and where any leaks are starting. Install a new high quality gasket and tighten with a torque wrench. An over tight bolt can cause leaks by crushing the gasket. If there is no damage to the gasket faces and a new gasket doesn't fix the issue, the leak is somewhere else on the engine. Possibly higher up. Oil can leak in one place and drip somewhere else. Cleaning the engine can help track the leak.

SOURCE: Datsun stanza 1980 tappets (lifters)

This car has hydraulic lifters( tappets} therefore should not adjustment, you probably have a bad or weak lifter. But, in any case you have to remove the valve covers to make the adjustment. You will see the adjustable bolt on the rocker arm. rotate the engine until the valve is all the way to the top, [no tension on the valve spring] then place a feeler Gage in between the rocker arm and the valve stem, adjust the rocker arm until the feeler Gage is snug but not tight. Do this with each valve. Check the book for the correct Gage to use but I think it is a .018.

Oil leak can be attributed to several factors.
1. Gasket failure.
2. Uncontrolled Crank case pressure Failure.

RECOMENDATION:
Tighten both the valve cover and oil pan bolts.
Replace the Positive Crankcase Ventilation Valve and vacuum line.,

INFO: PCV
This is a valve causes a negative vacuum on the engine while its running, As to say if it had a leak in a valve cover it should not be leaking while its running, only when the engine it turned off.

Hope this tip guides you in the correct direction to solve this problem.
