Needs front motor mount replaced? Who is the normal supplier of these and should I fill them with epoxy/urethane to stiffen it up and increase the durability.
The front mount on those turbos are hydraulic (filled with goo) you can't really re-fill them, you just need to replace them. There is a limiter bracket that you can stuff some muffler hangers or whatever in to tighten it up and keep it from busting loose again.
Adrian Thompson wrote:The shifter has always been a little wonky and the whole shift mechanism should be gone through IS this normally just shifter bushings? Where do I get them from?
Could be a small thing, or a big thing. The early style linkage bushings rarely fail like the later (dogbone-style), but worth checking out. It is a cylindrical bushing right before the transmission. Other than that, it is probably something internal, but it doesn't mean it wouldn't work for a while :)Fix the motor mount first and see if it gets better.
Adrian Thompson wrote:This is the big one the turbo has never fully boosted since I’ve owned it. It boosts about halfway into the yellow. I have never checked the base boost and clamping off the apc line makes it boost into the red so the turbo appears to be fine. What is this likely to be and is it a big deal?
Probably not a big issue. The APC system is sensing a fault and is resorting to base boost (mid-yellow). Usually it's the pressure transducer under the dash or some crummy wiring at the APC solenoid (or a fuse).
Adrian Thompson wrote:Engine has a top end noise that goes away after it warms up. Most likely a lifter or the timing chain guides are worn. Does this sound correct? Is this an issue and does it need taking care of ASAP?
Also not really a big deal. as long as it has oil, it's probably OK. I know some '87s had external oiling tubes in the heads which leak down a lot and take a little longer to re-prime. I'm not sure if some '88s had this as well. Since the lifters are hydraulic, they need to pump up if the car has been sitting for a while. It's actually worse if the noise doesn't go away, because then it means you have a sticky lifter OR not enough oil pressure....but in reality none of those are deal breakers.
Good Luck
