Followup to TR7 noise - engine bearings?
Ok, sounds like the noise I am hearing is definitely crank or rod bearings.
According to the manual I can replace those without taking out the engine.
I've looked at the oil pan underneath and it looks like in some places
someone used aquarium cement to seal it -- so who knows what else I'll find...
The good news is that I have 145 or 150 lbs of compression in each cylinder,
so the piston rings must be in pretty good shape.
So, some quick questions:
Is it standard practice to replace the thrust washers along with the bearings?
I assume that I will find the bearing size stamped on the bottom shells for
the crank and rods?
In the WWWedge archives I read an email from someone who claims that you
should not put oil on the back side of the bearings when assemblying them --
something about needing metal-to-metal contact for correct heat dissipation.
I thought that whole area was constantly soaked in oil when the engine is
running?
I assume I should do each bearing one at a time, so that the timing chain
tensioner doesn't take up the slack and make it impossible to get the
bearings installed?
While I've got the oil plan off, anything else I should look at replacing?
Finally, I have a serious leak somewhere near the oil pump and clutch slave
cylinder -- oil just pours down over those two parts. Any idea where that
leak may be coming from?
As always, thanks.
