1994 Mercury Tracer Q&A
1994 Mercury Tracer Question: Why would oil be forcing out of eng after head rebuild?
My mechanic days it is due to blowby but this is excessive. I see evidence of oil pushed out of dipstick. Over one qt oil in 180 miles. Before valve seats dropped engine only had small oil leak (one qt in 3000 miles). Could a oil passageway be blocked? I have the 1.9 liter eng. - widawg2
NEW HAEDS ON OLD SHORT BLOCK CAN CAUSE THIS. THE LOWER END IS TIRED AND YOU JUST PUT NEW HEADS ON IT WHICH CAUSES THE BLOWBY OUT DIPSTICK. CK TO MAKE SURE THE PCV SYSTEM IS WORKING CORRECTLY AND HAS GOOD VACCUMN - globalhelper
The VALVE SEAT dropped???? Did the pistons get damaged AT ALL?? If so, then no wonder it has blowby! While i agree a fresh top end will increase compression and thus a slight increase in blowby, but it should NOT push oil out of the dip stick tube! Have a leak down, and/or a compression test performed,that will tell the story!!! WOW. - pushrod
