Glad I asked! I'd have ****ed that up for sure

if you installed the rear main cap without it don,t sweat it as it is really not needed.

Teflon seals go in dry. Pretty much a diesel only thing, though.

I'm going to have a number of dumbass questions over the next 90 days so bear with me. Trying to get the bottom end assembled this weekend so......

1 - I ordered my new rear main and it also came with a little o-ring that's about 3/4 an inch. What the hell does that go to?

2 - anything special I need to know about installing the rear main? Not much online about installing a 1 piece rear. It appears it is just held in via the rear cap?

3 - should I use permatex on the corners of the rear main cap? The book I'm following is for a gen IV unfortunately so I just wanted to make sure

Thanks guys, have some patience with me here. Plenty more amateur engine building questions to come, but trying to get the bottom end together so I can get bob some measurements next week

2 before you set the crank in oil the seal and the crank where the seal rides,then carefully slide the seal on part way.then set the crank in,then slightly lift the back of the crank and slide the seal all the way in,then install the caps.some people use a little rtv on the outside of the seal but i never do and so far none have leaked.

a friend of mine put the rear main seal in dry on a mark4 engine,2 weeks later he removed the engine and replaced the torn up leaking seal.guess what,he oiled it the 2nd time and it,s all good.i certianly can,t see any harm in oiling a teflon seal.

personally i like my crank lubed up before insertion!

Thanks guys.

Haven't done the final clamp down yet so I'll follow your advice mike.

Interesting. I would never have thought to not oil a seal before install.

Call Jesel ask them why you should install the front seal dry. Many manufacturers recommend dry install.
