IDI Engine / Re: Awakened from a long slumber....

« Last post by westcoaster on March 18, 2024, 09:48:53 pm »

It was pretty wet at the tip of the tail pipe, almost dripping.
I suppose it could have been condensation. There was no particular odour to the liquid. It could have been purging the residual 6 year old diesel out of the system and somehow excessive moisture was produced.

It is running clean(er) now.
Sat and cooled over night and the next day things had cleaned up considerably.
I had also run it to the governor limit a couple times for a few seconds the evening it was having its issues.

Some MMO might not be a bad idea...

With the motor doing better I have shifted my focus to the death wobble this thing has now developed.

i agree with fatmobile, my first guess would be bad turbo seals on the exhaust side.

marvel mystery is a great additive, i'd recommend even putting some of it in your fuel.

how wet is the exhaust and are you sure its oil? cause water is a natural byproduct of combustion, and diesel smell bad either way

I think a diesel will burn oil like you were feeding it diesel.
Some people put used oil in their diesel tank and it doesn't end up with oil in the exhaust.

 If it's entering the exhaust as wet oil, I would think it's a turbo seal leaking oil into the exhaust.

Not an inlet turbo seal....

Removed the rubber 90* intake elbow from the turbo, started the engine, gave it a couple minor revs with a paper shop towel in front of the turbo outlet (intake air) and not a drop of oil was found on the towel....

Edit: the burning oil smell on startup leaves rings or valve guide seals.

I'm leaning toward valve guide seals as there is a strong odour of burnt oil immediately on startup that dissipates after running for a bit...

Correct, It hasn't been insured since 2018 but has been started intermittently since then.
4?, 5? 6?? times... No particular schedule, just whenever I think of it. Brought it up to temperature then shut off.

I can check the inlet turbo seal.

Would the white towel held up to the exhaust flange simply tell you that the engine is processing oil and not differentiate between rings, valve guide seals or turbo seal?
Not sure how removing the exhaust flange will tell me any difference? (post turbo)

Yes, it's been a couple days since I have last been on here...

So you haven't insured it for a long time but have you been starting it every so often in the last several years?

I can tell you that if your turbo seal is blown you can pop off the exhaust flange on it and you will see the oil on a white towel held up to the outlet when you race the engine.  That is for the exhaust side. 

Pop the inlet hose off and do the same on the blower side just before it goes into the manifold.  Don't do what I did and just remove the hose and race the engine.  My turbo uses that quick 90-degree bend hose that goes to the manifold and I got a nice spray in the face as I leaned over the IP to race it up.  Put up a towel to keep from being blasted.

As for valve guides, they can become dry and maybe get soft again once you run them some.  The danger there that I can see is that you may wear them adversely and they will never seal up again.  Kind of a catch-22 where you need to run the engine to get them oiled but in doing so you may mess them up.

Rings might be a problem too.  Running the engine should get those to work as they should but at times I have heard that they get bound up when they dry out and they don't expand like they should.  Might be from the coke in the burn of the diesel that does that. 

Nice to see you back on the forum after all this time.

For the first time since 2018 I insured my Suzuki Samurai (With 1.9TD AAZ swap)
While the motor "sounds" healthy, seems to drive "ok" it's smokey with a WET exhaust.

I have noticed a burning oil smell upon startup (after sitting weeks/months)

The wet in the exhaust doesn't smell like diesel so is likely oil.

Likely culprits are valve guide seals or piston rings. Turbo seal?

How to determine the source of the wet in the exhaust?
Or do I simply run the snot out of this thing in the hopes it clears up?

What sort of additive? Marvel Mystery Oil?

Today I ran down to Bandon in my new Maverick.  That hybrid is embarassing the VW with its stellar MPG.  The creature comforts have it put to shame anyway. 

Time to start doing yardwork, the sun will be out ALL WEEKEND.  I may need to find some sunscreen and some shorts.

So, now to do something else with it.  We are in for another 5 days of rain so I will have plenty of time to think about what I want to do next.

Don't worry.... you know something will come up.

definitely overkill for that engine, but theyre not very expensive and theyre easier to install and remove. I have seen people claim performance and mpg benefits, which i am sure there are benefits but i doubt it is something you'd be able to easily notice among all the other factors that affect those 2 things.
