Is this a belt driven engine, or a chain?
If chain driven, are they still using pressboard gears?

Also, is it interference, or not?

Belt-driven overhead cam.

Non-interference. There is an interference version (DOHC,
4 valves/cyl) of the Volvo red-block 4-cyl engines, but I
don't think a turbo version of it was ever made.

Yes there was- for the italian market, where anything over 2 litres is
severely taxed. There was also a 2 litre turbo 5 cylinder 850 T5 made for
the same market instead of the 2.3.

Neat. Didn't know there was a turbo version of the B204 - I'm
assuming it was underbored to be 2.0 litres, so was a B204
derivative and not a B234 derivative?

I do recall your mentioning this one previously here, but
thanks for reminding me about it again, Tim.

Not sure, but I would imagine Volvo just slapped the 16v head ontop of the
original 8v B200F / E block rather than shrunk a B230. (which I suppose a
B200 is?!)

Tim..
 
It has a camshaft drive belt which should be changed every 50,000 miles. It is
supposed to be non-interference as it has a low compression ratio to suit the
turbo.

Cheers, Peter.

Thank you all, guys. We took the car in trade yeaterday. I was moving it
around the lot and hit a bumpb, and the front end jounced a bit. It did it
again when I hit another bump. I also noticed, not a grinding sound, but
more than a whirring sound from the engine bay. I was beginning to think,
just mark the car up at $695 (the price at which you *don't* have to
warranty a car in my state) and let it rip!

But, I needed to come home today to grab some stuff, so I slapped the tag
on the Volvo and went for a spin (17 miles one way) car ran pretty good,
the jouncing from the front was gone!

One thing I am assuming: this car has an independant rear suspension (?)
It was wet today so I didn't get a chance to crawl underneath it and look.

Last time I heard this kind of sound from an engine, it was an '89 Celica.
A friend of mine who is a real Celica nut and a mechanic said "don't keep
it, it's going to blow". I sold it three weeks later, 3 months after that,
KABOOM! (course, the kid who bought it had lead in his right foot!)
 
All wagons up till 1994 had live rear axle (like 200). Only 960/V90 wagons from
1995 had IRS.

Cheers, Peter.

Thanks, Pete, but, not the answer I wanted to hear!

I asked because the rear wanders a little bit, but I have come to realize
this happens a lot with IRS (90 240SX, 85 Toy Celica GTS)

Since this is *not* IRS, I guess it means I should be looking for trouble
with the rear end, hopefully nothing more than shocks/springs...

Chances are the bushings back there are shot, the good news is the parts are
cheaper than shocks and springs.
 
Better still try renewing the bushings. You will be surprised at the renewed
stability.

Cheers, Peter.
