Re: Timing cover crankshaft seal replacement

For oil pan I used a single piece FelPro Q1880 thick (late style) driver side dipstick. The corners are bone dry. The leak is clearly visible - right at the bottom of the seal. The PVC valve is installed and functioning so there should not be crank case back pressure. I have a suspicion that a double roller timing chain crank gear is causing excessive oil splatter right on the back of the timing seal.

FSM states that timing seal replacement is doable without timing cover removal.

Balancer is brand new, and before final assembly I trial fitted oil seal on the balancer shaft - appeared to be a good fit. I may cut piece of 1/4" aluminum sheet with a semi circle to allow a seal pry bar to rest on vs. timing cover.

Replacement oil seal installation requires gentle taping. I have a core engine sitting on the stand - something to practice on tonight before jumping on a real job.
