RE: Even more 80q problems
The symptoms sound very similar to my 83 4ks when the #1 crankshaft/rod
bearing went out. The noise I had was more of a slapping or clunking
sound but is was also very dependent on load (i.e.., when in the lower
gears and between 2500 - 3500 rpm during acceleration). You can check
this by supporting the engine from the top, dropping the subframe and
the oil pan, then removing the bolts that hold the endcaps to the
connecting rods, and look for signs of wear on the bearing shells or
larger pieces of metal in the oil pan. It would also be a good time,
since you are in there, to replace the bearings and the oil pan gasket.
Its not a complicated procedure but it can be time consuming.
As for the clutch, I have not yet done this to my q but have done 4 of
them on my fox's and 4ks'. The first one took me 3 days - quite a
learning experience. Most of the time was spent separating the downpipe
from the exhaust manifold and chiseling out the pilot bearing. If you
have got some time to kill and some skin to spare from your knuckles it
may be worth your time to do it yourself. However, I think a decent
shop could do it in just a few hours. It is really just a question of
how intimate you want to get with your car ;^)...
In either case you should check soon. A bad bearing can ruin the
crankshaft and/or the connecting rod(which you should replace as a set
of 4/5). And imagine trying to pull out of the way of a semi truck/fire
engine only to find your clutch slipping and you are not moving at all
Hope that helps
