Test drove an 87 5ktq for sale today. has 192K kms on the clock. It was a backup car for the owner so it didn't get driven much. The engine ran with a little clunking kinda sound. Not very loud, but not how it ran on my old 200t. When I drove it pulled pretty nice. The owner said that usual boost is 1.3 bar but sometimes it wnt up to 1.5/ When I test drove it hill it would take off at 3K rpm, so I am guessing the turbo is still in good shape. That clunking noise in the engine is what I don't really like, so I was going top do a compression check and see if it is still good. I know that it should be consistent number through out all 5 cylinders, but what would a good number should be? What was it for a brand new engine?
I love booooost:D

According to my bentley manual the limit for comression on this motor is 94.
So if it's any lower than that....ehhhh no:(
I'm not sure but nornmal might be around 120?
remember to open the throttle all the way when doing the test otherwise you will get a false reading. Just pull the coil wire off so nothing fires...

about 125 to 126 I believe... but don't hold me to it. Most importantly you don't want the readings to fluctuate wildly from cyl to cyl. +/- 1 is OK from what I've been lead to believe.

Heyyyyy, is this the one in the van buy-sell for $1900? You gonna buy it? Owner mentioned a parts car too...

Could it be a busted motor/tranny mount?

Rusted cat. conv. hangers (they are metal brackets), bad motor/trans mounts (any of the 5), bad alt. bushings, all sorts of stuff can make a rattle/clunk.
by the time I made up my mind(6 hours later) and gave him a call back, he said that somebody bought 2 hours after I left, lol
Oh well, gonna keep looking :-)

Heh, yeah...how was the interior though? The price was pretty good. But I think he said the bomb was toast...oh well, there'll be others.
