Sorry for the long post. I had a 482 built for me in 2005 from a well known engine builder in the southern us. I have had a few life challenges since 2005 that's why there is hardly any miles on it. There is about 400 or so miles on it, no racing. Genesis iron block ,elderbrock alum. heads, 2x4, scat stroker crank, diamond pistons, comp cams hyd. roller cam, erson roller rocker setup. The paperwork from the builder said no warranty for rear main seal leaks. They never discussed this with me when I was ordering engine. Engine has leaked oil out of rear main seal area almost from day 1,but only a tiny bit when 1st ran. Noticed a few drops under car after shut down. Anyways, after I had drove it a bit, leak got a little more. I had a local mechanic who knows these engines well, he has a couple of stock ford 427 and 1 he used to race, to change the rear main seal for me. He changed the seal 3 times and the oil leak got a little bit more each time. He said he tried every method he knew. He checked everywhere else on the engine to make sure oil leak wasn't coming from somewhere else. He even used dye. I guess I won't know for sure until engine is out of car. It now leaves a small puddle every time I have ran it. He told me that the next step is to pull engine out and take it to an engine builder to pull apart to fix oil leak. He then retired and moved away and I don't know any other fe mechanics around here. Since then I have learned about scat cranks, early fe scat cranks coming with no grooves cut into rear of crank to help oil from leaking out of rear main seal. I learned this from reading the definitive guide to fe rear main seal install posted on this forum a while back. I'm guessing that my year 2005 scat crank in my 482 has no grooves cut into rear of crank, contributing to my rear main oil leak. I'm gonna pull engine soon to try and get this fixed. I'm assuming engine will need complete tear down, if this is indeed the source of the leak, remove crank to get machined rear grooves cut in, inspect all other parts and put back together with new bearings, seals and gaskets. Dyno test engine to tune it. I am no engine builder but know a bit about fe motors. ? #1- Does this sound about right to fix my oil leak if it is rear main seal leak ? Any help or suggestions from this forum would be greatly appreciated . ? #2- I 've read posts here from members who are in the vancouver, b.c., canada area. Could any members from there recommend an engine builder, machinist in the vancouver,b.c. area that can do this work for me or do I have to look down in the u.s. to get this work done? Engine is in my 66 fairlane 4- speed. Thanks!
