Need advice on Subaru EJ25D rebuild

Post by Lo Cash John » Fri Jul 14, 2017 10:17 pm

Guys I'm refreshing up my first Subaru engine and would like input from veterans.

I hate to call this a rebuild as I'm going to pinch pennies where possible. Basically it had the typical head gasket failure and leaked oil into the cooling system. I'm having the heads rebuilt locally and they'll be done in a week or so. The cylinder walls look good and even though I know it's got 160K miles on it. My gut instincts tell me to split the case so I can clean and inspect the bottom end so that's my plan. If all the bearings look good, I'll just reassemble with what's there. If it needs bearings I'll put those in.

I need gaskets and I'm leaning towards Felpro. The trouble is I have not found a complete Felpro engine gasket set. I've seen a head gasket set listed but not full engine.

Beyond the gaskets in the head set, what other gaskets are needed? Does anyone offer a bottom end gasket kit that compliments a head gasket kit?

Advice from experienced Subaru builders will be much appreciated.

There is no bottom gasket kit just o rings and you seal up the case with yamabond. It's the cheapest stuff you can get that works good.if the bearings are within specs run it.these engines have no empi parts so your good. :lol:

The OEM gasket set seems to be what's needed - here's a kit for the bottom end for an EJ255 (they have kits for other models as well). Top end gasket kits are separatehttp://www.rallispec.com/eng_gsk_subej255.html
I'm sure Outfront has gasket kits as well, their website sees to be in continual "remodeling" mode lately.
