Question about 1994 Isuzu Rodeo

1 Answer

Water in oil

We are chasing our a__ looking for the source of water getting into the oil. It is not a head gasket issue. We replaced the head gaskets with no change. Removed intake, flooded with oil/water mix. Water system is compromised somewhere internal to block. With heads on and intake off, blew air in water line from throttle bocy and can hear it coming out of oil filler cap. I doubt the block has failed but due suspect some plug in the water jacket has failed. Not an import guy, give me a chevy!. ANY help would be appreciated. Dave

If you hear air comming out the oil filter the you have a cracked block. the water jackets inside the block being cracked it the only way to get air out of the oil filter. Sorry about the news but a flux of the engine and you'll find out

Engine froze up, what causes water to get in oil?


The head gasket could be blown. Is there a lot of water? Is there oil in your radiator?
There is a chance, it could be condensation. If it is just a small amount of milky looking oil on the oil cap.

Leaking oil and water


Get a torch and look all round the engine until you see the source of the leak.
There are only a couple of options namely:
1 Through the engine, meaning a blown head gasket so you may not see where the break in the gasket occurs
2. A leak on the outside of the gasket - you should see this
3. a cracked head requiring specialist work

How do i troubleshoot the head issues


With the radiator topped off and the cap off run the engine at idle. bubbles indicate a blown head gasket or cracked head. Also look for water in the engine oil and oil in the water. Real heavy water in the oil and no oil in the water indicates a blown intake manifold gasket. I have only seen this on GM engines.

Had the radaitor rod out had goose neck change had a single head gasket done check hoses and car stills runs hot and now i see slug in the cap of the eninge


if it looks like a chocolte milkshake you are getting water or coolant in the oil. pull the oil dip stick and look for traces of water in oil. if water in oil. you have another gasket job to do. more destructive route is through a coolant leak due to a bad gasket, an engine crack, etc. This amount of moisture is generally going to cause serious engine issues including loss of power, oil sludging, etc. Consult your mechanic when in doubt. good-day! if its a v6 maybe the other head gasket is bad. this will cause it to heat up.

I got litle moisture in the oil the oil looks like milke it doest get hot, but its get litle drops of water in the oil what can I do?


You may have a head gasket leaking. Head gaskets can leak two different ways. One is to the exterior. You will see it and it will be quite obvious. The other is a water leak into the cylinder. the water gets into the oil pan via that route. Do you see water or steam (looks like white smoke) issuing from your tailpipes?

Blew oil out of the water resevoir


We just had the exact same issue with our 2004 F-350 with a 6.0. The oil cooler had failed. Its an expensive fix. But less costly than a blown head gasket.

Water in oil


I have yet to see a cracked head on a 22R,so more than likely a blown head gasket,unless you overheated and warped the head and worst case a hole between the cylinder wall and water jacket(this is pretty rare).The only way to tell short of using some expensive tools or taking to your local shop is to pull the head and inspect the gasket for leakage wich is generally fairly obvious(separation of the gasket layers,oil and water between water and oil passages)and checking the head deck for warpage.If there is obvious leakage in the gasket you're looking at a top end gasket set if the head is slightly warped you can get away with a thick graphite head gasket,I personally use these as they are very forgiving on slightly warped and scratched head decks and inepensive also,but a severly warped head will require milling at a machine shop or replacement.
