Filthy 2.8

On the off chance that someone else has had this problem and can offer a solution that I haven't tried , I put a used engine in my 83 S-15 . The first time I pulled the radiator cap , it had 1-2 cups of oil in it . Thinking that the motor had been running with a bad trans cooler , I flushed it ( about 6 times ) then it started to contaminate the oil . Then I jerked off the intake , went and got a better looking used one . It was sort of OK for a while and now it's starting to show again . Not like before , just 2-3 tbl. spoons every time I look . It hasn't used a disernable amount of oil in 2 months and it hasn't used a disernable amount of coolant either . It runs well ( 22-25 mpg locally ) and doesn't have any of the normal signs to indicate a leaking head gasket or cracked head . ( the system will hold 10-15 lbs for days on end ) Since I thinking about going to Arizona and back from Seattle over Xmas , does anyone have any ideas ( besides these are 90% crap) or should I take my title and busfare as insurance ?

is there water showing in your engine oil? look under the oil cap for moisture. sounds to me like a headgasket. or the block might be warped a tad..

How did you install the new gasket? If you didn't loosen the rockers and pull the pushrods, you may not have sealed it properly.

Well.............Pull the push rods eh . I wouldn't think that would cause this but I suppose since I've "missed " a time or two in the last 40 yrs It's a possibility . Gaskets are cheap and I've got the time . If it were a head gasket it would've gone really bad by now ( 1000+ mlies) and would build so much pressure in the system I'd see it . I guess we will see . Thanks Will

Gaskets leaks can start out very slight ... then get worse with time. Still, even trace amounts of glycol in the motor oil do a great deal to accelerate wear.

Consider having a sample of your oil tested by a lab such as Blackstone for traces of coolant:

Cost is only about $20. Then, you just have to figure out if it is a head gasket or intake manifold.

Also, since glycol is so damaging, you'll want to change your oil & filter more often to get rid of as much as the coolant in the oil as possible.
