Unless you get it perfect you may have problems with rear main bearing cap/bearing clearance.
If it is off, even by .001 it will screw with bearing clearance.
If the bearing cap is off, clearance will be off, could have bigger issue than an oil leaker.

Yea i was thinking that if welded on itd have to 100% flush for the cap. But it should be. As long as person holding it on keeps the chipped peice flush with where it cracked
I was just saying it would have to be verified & corrected if it's not.
When in rhe realm of bearing clearances things need to be perfect.
Not an easy or simple DIY repair here.

Probably what I would do, clean it up, and put it back with the way it is now, and see! No need to sweat it.
I am sure that nobody will offer any warranty.

Well after soaking pistons in chem dip for 2 weeks, I was finally able to get the ring grooves clean.... pain in my @#$.
Napa shorted me 2 of the rod bearings, I should have them tomorrow. So the bottom end is almost together.

Been a slow process life keeps coming up and my wife's bronco (our only running vehicle) been showing need for lots of attention.

I have a love hate relationship with my old vehicles lol.. You fix one,, and the other starts to fall apart.. Its a back and forth battle between my wagoneer and the two 20 year old grand cherokee's lol. Oddly the 4.0 ZJ is at 252k now and its still on its original tranny and engine and its never had any major issues, minus needing a new timing chain,radiator and some bad seals in the past. Gatta tell you im amazed that 42re transmission has 252k miles and still runs strong lol. That almost unheard of for an RE series

Still not done... baught a new heavy duty water pump though, and it's impeller was too thick.. it wouldn't mount properly... grrr. So had to return it for the oe pump, oh well. maybe I might get some time to continue this engine rebuild sooner than latter.

time for a beer and a movie

some cans have the right diameter and can be used as driver for the front seal... usually the biggest hammer with slight tapping works well...

I haven't tried the can thing but have tried a flat board a little hammer a big hammer a big socket a deadblow

I think I'm gonna have to just say screw it and get the tool for it and put it in with the cover on the engine

in fact it is tricky, it has to go a bit sideways but not too much,just enough... may be a little lube,not too sure what would be ideal, someone will chime in. Always easier when the cover is off...

Finally got the seal in time to crack a beer

I scraped the outside edge to a light bevil with a razor blade worked fantastic

Me counting was, how many times I smashed it on the floor or with a hammer.... I realized I had an issue when I tried to make my 79 f250 more fuel efficient by putting dozens of softball size dents in the hood with a mini sledge.... this when I realized I had a problem.
