leaking fuel damper?

[2fas2c]

Since I bought my T4R just over a year ago I've been having some issues with my 87 22re 5spd hesitating and bucking, I also smell fuel in the oil. I went ahead and started to tear the wiring going to the injectors apart, I was hoping it would be the injector wiring junction corroding and falling apart as it seems to be a pretty common problem. Removed the loom and tape and everything looks to be fine. I have also heard of an issue with the fuel pulse damper on the fuel rail at the opposite end of the rail from the FPR leaking because of a loose screw. So I removed the little plastic cover over the damper and inside I found a small amount of fuel and an oily substance, which really could have come from anywhere. My question is, do these dampers go bad? is there a seal or anything in there I can replace like the screw maybe? are these available new, or do I even need it? I removed the one in MR2 and replaced it with a braided SS AN fitting line and it never seemed to have any problems.

Any thoughts?:cheers:

I am starting to think it may be the injectors or cold start injector.

If the damper is anything like the V6 one, it's a simple replacement of the entire piece. I would definitely recommend keeping one on there, as that protects the pressure regulator from spikes in pressure that can cause it to fail. Best of luck on the repair.

Both the damper and regulator can go bad, but I can't see how they'd cause a fuel in the oil smell. That sounds like another issue.

I was thinking of this as a separate issue, I was thinking an injector was stuck open that's why I checked the injector wire junctions. I went ahead and pulled the intake manifold out and found a few issues, a few of the manifold bolts were missing and the PO used too much FIPG on the thermostat housing and a blob of it had the jiggle valve stuck open.

I took the injectors out of the rail and I noticed the seals at the snout of them are crumbling, anyone know where to get new ones? I don't mean the o rings of course but the ones at the other end and the ones underneath the o rings for that matter?.

thanks I'm sure most of these things are very similar, should the screw in it be tightened all the way down? this was a few turns loose and when I removed the plastic cover there was gas in there.
