This summer I am going to pull the engine out of my wife's Subaru. It is a 96 Legacy Brighton, with the 2.2. It has head gaskets that are leaking oil out, and it is just a mater of time before catastrophic head gasket failure. I am hoping that I get to it before that. I also know that it has a leaky rear main seal so I will be doing that fore sure as well. I don't think this engine got ragular oil changes when It was young, hense Leaky oild gaskets at 100k.
I replaces the timing belt and tensioner about 10,000 miles ago, I don't plan on doing those unless oil has gotten on the belt. We also have an intermittent rough running condition, that throws a cylinder 3 mis-fire.
My question are:
1. Am I best off to get all my gaskets from Subaru, or are there some improved aftermarket ones, If so what brand and where can I source them from?
2. What other things should I plan on doing while I am in there? I was thinking about a new pan gasket, having the heads surfaced, intake and exhaust manifold gaskets, new front crank and cam seals, and of course the head gaskets and rear main seal. Is there an input shaft seal on the transmission? Any sensors, or switches that I would be a fool not to replace while the engine is out?
3. Are there any special Subaru specific or unusual size or shape wrenches I will require?
4. I have seen some talk about replacing the head bolts in the post I have read, Do I have to source those through Subaru, or is there an acceptable aftermarket parts that will not cost as much?
5. Does anyone have any ideas about the intermittent (once every 2-4 months ) rough running?
6. Any other helpful hints, tricks or links with good information would be appreciated.
Thanks for your help,
