I guess Iím doing my head gasket

95 e320 with 100k miles. Should I change the timing chain just for ****s and giggles? Iím doing valve seals since it smokes .. leaks oil from from to back.

That's really weird that she's smoking with such low mileage....esp on a 95.


I wouldn't waste the money on a chain unless it's beyond amazing...you can measure stretch before you tear her apart....if this engine was horribly maintained then it Could be now worn then it otherwise should be.

Check those valve guides closely...

Under what scenario did the engine smoke?

It smokes till the engine warms up. If I start it up and jump on the freeway itíll leave a thick smoke cloud. Runs clean once warmed up.

That's Weird...if it was guides it should only smoke for a bit on start up or after a high vacuum situations....

I'd look at those cylinders real Close...

I hope itís not the lower parts. It idles buttery smooth with no knocking. Spark plugs appear to be clean . I picked this car up about 3 months ago for my wife. Itís been a headache from day 1. The previous owner did a lot of half ass stuff Iím finding out

Consider a leak down test before pulling it apart. The smoke could be rings if it was overheated, otherwise they should be good. Replace the timing chain??? If the engine is clean inside it should have many miles left in it, if it is clean and not stretched I would leave it.

Good luck!!!

My other thought is if it has been eating coolant you could have torn up the cylinders... Seen it before.

Either way, what you describe does Not correlate with head issues.

I think I have many separate issues. The head gasket is externally leaking oil all over the place. Front timing cover is also leaking real good. Wife drives maybe 40 miles a day and it’ll drop a quart easily. Coolant is clean and not leaking. The smoke I think is from the valve seals but that’s just a guess. And another issue is that the po didn’t set the cam adjuster so I gotta fix that while I have the timing apart

Normally the chain is not a problem at this mileage. What might make sense at this age, though, are the plastic chain guides. If you’re making access from another job, like the head gasket, then I would replace those at the same time.

The information desired from the leak down test is twofold: 1. Is there excessive leakage and 2. where is the leak?

If there is excessive leakage and it comes out of the intake or exhaust it is valve/seat (not valve seal) related. If it comes out of the oil fill cap or dipstick tube it is ring/piston related. If it comes into the cooling system it can be a head gasket, cracked block or head.

What color is the smoke and is the engine clean internally? What weight oil, synthetic or dino? Do you think it is reasonable that some of the smoke is oil leaking onto the exhaust system?

Good luck and please post the results!!!

right now Iím using the cheapest oil I can find .. 15/40 5gal buckets. It leaks so much oil that itís hard to tell any color changes on the dipstick. The smoke is out the tailpipe till it warms up. I can see it blowing out when Iím driving. But thereís alot of oil burning off th engine too which is noticeable at a light.

If it smokes when you accelerate from steady state cruising don't waste your money on this engine...

Now if it Only puffs when you first start her up, leaving a traffic light/stop sign etc....that's guides/seals.

it’s more than a poof of smoke. it only smokes for the first 5 minutes on a cold engine and seems like it’s high crankcase pressure but I know it’s not. Wish the c36 engines were more plentiful I’d just swap out.

The mechanic says the smoke isnít tailpipe smoke.. itís oil spraying on the exhaust. Iím not 100 percent with him on that but ok. And the lower engine is in good shape.
