Took my pickup sledding a couple weeks ago and on the way up the mountain it started getting hot so i pulled over and cooled it down an noticed that there was anti-freeze on the ground. So i cracked the cap and the tank was under an extreme amount of pressure then it should be. so i added coolant on once again blew it out. So i hauled it home. i dumped the oil and noticed it was a little grey so i changed it and let it si at high idle for five minutes once again pressure in the coolant tank and the oil was almost like chocolate mMilk. I installed new head gaskets and studs and now i have that pressurizing the coolant system problem fixed but is still getting water in the Oil! where do i go from here?

 

I'd probably start with rebuilding the oil cooler...easy and inexpensive to rebuild. It certainly could be something much more serious, but trying the easy things first is the approach I take. Here is a thread on the rebuild...

 

Im having that checked right now and i have even pulled the water pump to see if i had cavitation that coulda worn a pin hole in the front cover but all is good.

 

Don't discount the possibility of the engine holding 3+ quarts of residual oil regardless of whether you changed the oil earlier.

That residual oil will contaminate the new oil in a hurry.

 

Well i had the oil cooler checked and it was bad and so i installed the new one and it is still pumping coolant into the oil. Drove 5.8 miles and lost 3 quarts. All went into the oil! Where could i look or what could cause this?

 

Injector orings?

 

Front cover....cavitation behind the water pump

 

Sorry hit send too soon....

Cavitation can cause a hole to develop in the front cover behind the water pump

 

Believe he said he already checked that

 

Yes i removed the water pump and everything is like brand new behind the pump. This engine on has 94,000 miles on it.

 

What about injector cups?

 

Injector cups allow fuel to get in the cooling system. My vote is still o rings.

 

Found it today by pressurizing that block with the pan off and the block is cracked right above the main bearing into the very bottom of the cylinder! SO need help locating a block!

 

That sucks man, sorry to hear.

 

Well cant change it now so im on the search!
