Title: Who has the answer to this CRAP ??
Post by: enginedoctor on September 18, 2009, 12:55:40 PM: 1971' BBC:

Problem is.......

Customer just bought this car from a guy.....brings in the engine and tells me the following!

1. Engine runs strong and hard.......BUT :sly:

Engine is pumping engine oil into radiator, about 4 quarts in 50 miles.

2. Yet, there is no water in the oil at all ???

3. Radiator keeps clogging up with oil, over and over again.

Who has the answer to this ??? ???

Post by: enginedoctor on September 20, 2009, 01:52:56 PM: The problem in this case is in the " Lifter oil Gallery."
It is cracked & Pumping the oil into the water jackets on the thrust side of block on the 1 thru 7 side.
Upon engine shut down, the cooling system will send almost an undetectable amount of coolant back into the
block , which is virtually un-noticed. Finding the problem is a bear :sly:

1. Solution:
Junk it! ;D

I have seen this in Inline 6 cyl. Chevy and SBF as well.
