Yikes!! Coolant in oil

Unread post by hondo100 » February 19th, 2019, 1:00 pm

Motor last ran 3 years ago before being pulled. Compression was 75 psi on all 4 cylinders. Motor sat in shop untouched until just recently. Drained and removed radiator. Started draining oil and first couple of quarts were antifreeze, followed by engine oil.

What are possible causes?

That's very low compression, I would start with head gasket.

Yep, head gasket. Real easy job yo do on these but when you do it be sure to run a bottoming tap down all of the head bolt holes as I have seen three cases so far where the head bolt holes were not fully tapped and those bolts could not tighten fully.

if anyone else needs this head gasket and other gaskets that go with it, I have a few for sale. N.O.S.

Make sure it is the one with lands and not flat. The flat one will allow coolant to leak and you will have to do the job again (don't ask how I know)!
