This post is as much for me to document for myself what I'm doing to get some feedback as it is asking for help - More of a discussion.
I'm finally tackling the leaky valve cover. But while doing this job, I'm finding many questionable old original parts and wondering if, since the jeep is now 20 years old while I have things apart, I dump money at it. It would be easier to tackle this all at once, and it will all need to be replaced in the next five years.
The rear Main seal needs replacing as well. But the exhaust is all hacked together by a previous owner, and even it looks like it welded at the manifold. I've had CO2 sensor errors since getting the Jeep and have never been able to get them out. Exhaust manifolds themselves are looking a little chunky with rust. The valve cover leaked so much over the last year that the engine was just coated in oil down the backside, and there was oil all over the exhaust manifolds. Someone also, along the way, removed the rear cat.
It's a 2005 LJ Rubicon with 185,000 miles on it. The rockers and push rods looked great when I looked at them last night. I might have an exhaust leak somewhere around the manifolds, but it didn't run too long since the oil started to smoke like crazy on them. Cleaning the oil between the intake and manifold will be nearly impossible.
So here is my thought
1. Remove the drive side fender
2. Remove intake, exhaust manifold, remove full exhaust
3. Degrease like crazy
4. Take the time with the intake off to clean it all up
5. Do the rear main seal and oil pan seal
8. Install new exhaust manifolds
9. Install new cat system
10. New O2 Senors
Parts:
Rear Main Seal — FEL-PRO BS40183
Oil Pan Seal — FEL-PRO OS34308R
Exhaust Manifold Front — DORMAN 674467
Exhaust Manifold Rear — DORMAN 674468
Exhaust Manifold Hardware — FEL-PRO ES7511
Exhaust Gasket (I like Fel-Pro) — FEL-PRO MS93094
New Cat System. — DAVICO 19281 E.P.A. Compliant
O2 Sensiors — Have have already
Oil pump — MELLING M81A
Oil Pickup — MELLING 242S
Camshaft Sync — 53010624AC
Maybe
Water Pump??
It will be about $1500 CDN in parts, but I plan to keep this Jeep forever. The only reason I might not do it is I've been finding the aftermarket parts are sometimes garbage. But now does feel like the right time to do all this job. I think its my choice of exhaust manifold that cat system that concerns me. Any better recommendations?
