Hi,
1990 1HZ
I had a cold start fuel drip in the winter and it went away with spring so I didn't worry about it too much.
It started leaking the first few cool nights of September and, soon after, I started hearing a funny rattle at about 1500 rpm. I put some bio in the fuel and the leaking went to almost nothing but the rattle continued.
Finally took the wheel off and had a good look at the Injection Pump and found the leak was coming from the RH (to the block) Timer Cover. I also found the rattle's coming from there as well. You can see (and feel) the cover shaking.
I don't want to take the pump off just to tighten two little allen bolts!! But I may have to do it to change out the o-ring though the bio seems to be working.
Questions:
1. Anyone had experience tightening those little bolts with the pump still on. I think one can be tightened but the other is real real tight to the block.
2. I have a very experienced mechanic, who's off hunting till mid October, who can help take the pump out. Should I worry too much about the thing falling off before that? Damage?
3. Would a little more bio (I'm running @B20) make a difference by swelling the o-ring and creating a better seal and possible damping the rattle?
Thanks!!
Michael
