Engine knocking then quit running altogether

All,
I appreciate your inputs, and just a note. I'm not driving it, it sounds too bad. I haven't check the oil pressure with anything other than the gauge on the dash, seems to act normal. Oil is in the crankshaft...

I'm hearing engine replace...so, I'm going to start pricing that out.

I don't think the knocking gets any quieter, it pretty much remains constant as long as engine is running, and the squelching remains as well. which is why I don't leave it running.

Don't know if I can blame the sea foam application, but with a healthy dose of I should have known better...or if the injector leaking into the oil...Either eay it's kind of a mute point.

Hear we go to the engine store... I'll keep posting my progress...

Sounds to me like main bearing problem. The higher pitched sound is piston skirts as they hit the cyl wall at slightly different angles with the extra vibrations coming from the crank. You still have a repairable motor if you stop driving it now. It's time to pull it out and see what you've got.

I think there is a valuable lesson here, and is one that I've been preaching about for a while now. Filling your crank case full of these miracle cleaners can be harmful. I know the shelves at your local parts stores are full of these wonder drugs for your engine, but Buyer beware!

Nothing beats a good regular maintenance routine. NOTHING! That means changing your oil regularly!

There are posts full of information on oils and oil filters on this forum and there is just flat no excuse for not keeping your oil changed. That doesn't mean buying the cheapest .49 cent oil at Wal-mart and Fram oil filters, but if that is all you can afford it is better than leaving the sludged up oil in the engine for years on end.

gmyoyo, Please don't mistake this for a lecture, but please consider this as friendly information sharing to others in hopes of preventing this from happening to someone else.

I didn't take it as one...lesson learned (the expensive way)...funny, I always wanted to be aposter child for something positive, but surely this is not it!!!!

Whoa whoa whoa there, let's stop blaming the cleaning agent Rick.

This was caused by the fuel entering the oil, not the seafoam. This is why we say if you have a 1992-95 CPI engine, best replace the injector and nut kit even if it is not completely shot.

Just when I thought we found a little middle ground. LOL. I agree on the diluted oil theory, we both stated it in previous posts on this thread, but I can’t help but think the Seafoam/cruddy oil contributed to the problem.

You know first hand that many people (myself included) have had their CPI and Nut Kit go bad and leak gas into the oil and they didn’t suffer the extensive engine damage that gmyoyo is seeing.

All I am saying is "BUYER BEWARE" of these miracle cleaners.

I've seen people use engine cleaners and destroy their engines. Yes, the cleaner did its job, but it did it so well, that it softened a lot of sludge, and caused oil galleries in the engine(mains, piston, rods oil holes) to clog up and allow that part to run dry....and boom rod knock, main, cam bearings all running dry and spinning and destroying them. Gas does that same thing in the oil...notice how clean the lower plenum is in a CPI engine when the spider is leaking...?

This is not the case.

The huge fuel leak is the cause here.

Nah, he could have hydrolocked a cylinder with fuel which caused the bearing failure and maybe a bent rod.

I have used water decarbonizing and GM top end cleaner and have NO PROBLEMS.

Stop with the fear mongering about this case. IT WAS NOT CAUSED BY THE CLEANER, IT WAS CAUSED BY OIL FAILURE.

I agree with Rick about being careful about throwing additives in your engine....defiently buyer beware.

Fear Mongering.....LOL...unfortunatly his engine is toast, what fear mongering?..the damage IS done, he's stating his opinion. I am glad you voiced your OPINION too.

I have used all of the GM supplements, cleaners and additives too, and never had a problem, but it COULD happen - other additives included, not saying this is the case here, but it is possible, how exactly can you just shun and say no? What other creditable information do you have that would say otherwise other than your opinion?

I also have used engine flush successfully per your instructions on this Forum. I have also lost an engine using flush. It is up to each of us to make our own decision when buying or using these products.

As for the fear mongering, I've said my peace, but I thought this Forum was about sharing information. I have my opinion about what caused this engine to fail and you have yours. Who's right or wrong? We'll probably never know for sure. The main thing is to get gmyoyo back on the road as quickly and as cheaply as possible. The way I see it, the poor guy spent a lot of time and money putting a CPI and Nut Kit into an engine that has major internal damage and needs to be removed and replaced or repaired. Hopefully, most if not all of these parts can be used on his new engine.

Yes, anything could happen, but it wasn't the cleaner causing this, it was the huge amounts of fuel in the oil I can almost guarantee it.

Cleaners won't cause catastrophic failures like this one, they might uncover a weakness that is already there, but it would cause them in the first place.

All I am saying is that Rick needs to stop pushing the cause to be the cleaner.

In at least three different posts on this thread I clearly stated my OPINION that the COMBINATION OF THE SEAFOAM AND THE DILUTED OIL was the possible cause.

I also took the opportunity in two posts to share my OPINION AND EXPERIENCES regarding Crankcase cleaners.

Neither of us knows the condition of this engine, or how well it has been maintained. It could be one of those sludged out monsters that we've all seen pictures of on this Forum, or not.

I am sticking to my OPINION that the cleaner CONTRIBUTED to the cause.

We're just going to have to agree to disagree.

But just for the record, how many minutes or hours or days would an engine have to run with gasoline in the oil to cause such a catastrophic failure? Or maybe a better way to ask the question is how long does someone with a leaking CPI and Nut kit have to repair their engine before they end up like gmyoyo?

Ding Ding Ding. OK RNwood and BLT, go to your corners and wait for the yoyo to tear this engine down and tell us what he sees and if there's huge piles of gunk plugging the oil gallerys or not. Until then it makes no sense to get pi$$ed off that someone disagrees with your GUESS.
