Story in short I rebuilt the top end of my 94 22re and I started having an oil leak at the front of the head. Pieces of the gasket have came apart where it’s leaking. It was a gasket set from Orielys. I am gonna to do it over and wonder where you can order OEM parts with our going threw the dealership. If you have any ideas please share them.

Which "gasket" is leaking?

MY O'Reilly's sell Mahle, Fel-Pro, Beck Arnley.

Any of those have a good reputation for quality, depending upon the experience, opinion, or expert.

What brand did you get from O'Reilly's?

What torque spec did you use for the head?

How many miles on the rebuild before it started blowing oil?

When installing the T-chain cover, there is a little bolt in the front of the head that bolts into the top of the T-chain cover (torque spec 9 ft lbs.) When you installed the T-chain cover did you torque that little bolt with the T-chain cover bolts loose? There is a little rectangle shaped gasket that protrudes out from the head gasket and the deck. That gasket area must be sealed very carefully. If you are not careful, that piece can get damaged. If it is not sealing, oil from the T-chain cover will blow out right under that area between the head and the T-chain cover.

Where exactly is the oil coming from?

I used Ultra Black on both sides of that area on the headgasket.

Looking at the picture the leak is coming from bottom left towards the center. Truck runs good. Has some white smoke but not all the time. You can smell strong exhaust but doesn’t smell like burning oil.I thought it was from all the EGR crap removal. I remember torquing the head bolts to a specific torque but I can’t tell you the number. I didn’t torque any of the other bolts on assembly. The oil that is coming out is fresh oil. You can clean it then run it and see a flow of fresh oil after running it. It will use about a quart a week.

Can I crank the motor while all the belts and water pump is removed fir a few minutes to find out for sure where the leak is at?

RUGER · « **Reply #10 on:** Dec 16, 2020, 06:09:38 PM »

sounds like you had the head off recently, did you have it machined when you had it off. how did you torque the head down, middle to outer

Look at Gnarly's picture.

When I changed my timing set, the section that Gnarly surrounded in yellow got destroyed.

I didn't want to take the head off.

I made a section of gasket and installed with ultra-grey.

When done, I got a small amount of oil leakage from that section of gasket.

I DIDN'T WANT TO TAKE IT APART.

I managed to fix the leak by cleaning the outside where that gasket is, and SMEARING some ultra-grey on the outside of the gasket.

Looks a little messy, but no leak.....

No machine done. Did not overheat. Loosing water threw the exhaust ports. So I decided to change the gasket.

I'm confused.... are you saying what you posted above is the reason you just replaced the head gasket?

How do you know it is losing water through the exhaust ports?

So you have fresh oil blowing out the front of the head - looks like the seal at the top of the t-chain is leaking.

And, you have water/coolant coming out the exhaust ports.

It is a hellava lot of work to replace the head gasket on a 22RE. Before I'd start doing a replace, I'd want to know exactly what is failing and WHY.

Throwing money after parts may not fix the real problem. It is very common to first blame the head gasket for the failure - and there are head gaskets out there that are chinese junk!.

The head gasket and head to deck seal on these engines is a critical. If it is not done right, there will almost always be a failure.

Why did you replace the head gasket? What did it look like?

How many miles on this engine?

Has the engine ever over-heated?

Were the head and engine deck flat-checked?

Sorry to mislead. The 1st time done it was because of loosing water threw the exhaust. I replaced the head gasket and it did okay for a while. Now, this time it’s the oil leak in the front.No flat check was done. I’ll check the timing chain cover first.

Gnarly4X · « **Reply #16 on:** Dec 17, 2020, 11:19:24 AM »

I would check the seal under that T-cover. You may be able to fix the leak without replacing the head gasket. Like emsvitil said. Once you get the bolts in the T-cover just barely finger tight, then torque the little bolt through the head, then tighten the bolts on the T-cover.

When say smear gasket maker..... exactly how are you smearing it. Are you removing any bolts or parts to do this?

emsvitil · « **Reply #18 on:** Dec 17, 2020, 05:03:37 PM »

For the last ditch effort on the outside, after the fact...........

Think tub caulking

General rule when you remove an aluminum head is to check/have it checked for true, regardless of whether or not you had over heating issues, the head can warp just from normal heat cycles, warpage that doesn't become an issue until you remove the head.

Due to the leak you had, if you remove the head again, it would be a good idea to have the head inspected and pressure tested, the type of leak you had, if not identified by the old HG or a stain pattern on the head, is usually due to a crack.
