Head gasket


tbrduc

Recommended Posts

Hello,

I'm going to do it..new head gasket. It just overheats too much and prior evidence indicates a need. (water in oil)

I've ordered the kit from Blunttech.

I have 2 manuals and the tools, space and mechanical ability.

I don't have experience on THIS particular task though.

I'll be chatting with ClayW later today, but, besides securing the timing chain and gear, what other 'gotchas' should I be aware of?

The exhaust manifold bolts are all loose!!

I'm going to do this on Saturday and hope to complete it.

I live in Vienna, VA, if someone wants to come by and offer support, assistance or whatever.

I will have Smithwicks and Guinness on hand for afterwards.

Thanks.

..tom

Sorry but I'm busy Saturday also. Just fininshed my rebuild on a spare engine, which I haven't installed yet. Also have a good spare rebuilt E12 head you can look at for comparison. I have a torque angle guage if you need it.

Post some pics of the head so we can take a look at it too!

Look for cracks between cylinders and specially between water and oil passages since you have had the problem of oil and water mixing.

Also check for advanced corrosion on it.

Besides making sure the timing doesn't move just make sure you torque to the right specs and that everything is super clean. Now that you are opening the engine it would be a nice time to clean the piston heads with some solvent, adjust valves and change the oil (if you cleaned with solvent it gets thinner and contaminated).

To check for warps you can also use a glass big pane of glass and a very good light.

Best advice I can give is make sure the area where you are placing the new gasket is VERY clean use some very fine grit sand paper but not as fine as to polish it.

That's all the advice I can think now!

once you have the head off I suggest you not only check it for warpage but that you take it to a machine shop capable of PRESSURE testing it for cracks and warpageand repairing said problems. Blown head gasket/overheating usually is a SYMPTOM of the above problems and/or shot water pump or radiator full of crud or cooling passages in head/and block full of crud OR ALL OF THE ABOVE...Just changing head gasket quite possibly will not do more than ameliorate One symptom.
