Off Topic Engine Question

My brother in law has an old 70's Nissan forklift with a four cylinder engine (propane). He has water in the oil, is there any way of finding out where it is getting in. He said it has good compression on all cylinders. He does have to top off the coolant every so often. The spark plugs have some water and rust in them. Any ideas would be great, could it be a gasket? Anybody know of a good resource for info on this engine?

Should work for propane also.

WOW they were not kidding when they changed to LostJeeps.com Not Just for Liberty Owners. Fork lifts they are not even allowed on the roads. What has happened to this web site? Get real

Head gasket.

I took a quick look at that. It seems like the engine needs to be running for that test to work. It doesn't seem that there is oil in the radiator fluid. Also he doesn't use any antifreeze in the coolant, it typically doesn't freeze here in sacramento and he stores it in his wharehouse.

Sorry for this being so off topic. This is the best source for vehicle advice that I know of or have access to. Thanks for your assitance.

Just because there isn't oil in the radiator does not mean exhaust gasses are not in the radiator.

Put a compression gauge on each cylinder in turn and do a bleed down test. This should identify which cylinder has the problem. You will have to pull the head to fix it. Isn't there a forklift forum?

He did post it in the Alternative fuel forum

There are a lot of great minds on here. I don't know know of any where else that one can get in to contact with either a ASE certified mechanic, elevator technician, CAD designer, paleontologist, custom fabricator, or a city inspector in less than 3 clicks....... AND not have to deal will with idiots that have no knowledge of the subject but still add their :2cents:

One place that people forget to check is the cavity behind the water pump. If it is aluminum and if they don't change (or use) anti-freeze it will eat a hole in the pump housing.

don't know about a Nissan - but on the CRD there's a oil/water - oil cooler
mine blew a gasket there and leaked oil into the coolant

If its a non turbo engine I would be looking at the head jasket. that is one of the most comman ways water gets in the oil for most engines in general.
