I am currently bringing back to a healthy state a 1989 245. I just replaced the oil seperator and flame trap system, the timing belt, drive belts, and plugs. I also had a blown intermediate shaft seal that I replaced as well. (On a side note, I have never had a car as easy to do a timing belt on as this Volvo! The service interval is a bit more often than I am used to on my Mazdas, but holy cow!) I noticed that there was fuel sitting in the plastic intake hose going to the throttle body. The car starts poorly and idles rough, but doesn't die, with the check engine light on until it warms up. Then the light goes off and it runs fine. I see there is a fuel pressure regulator attached to a hose going to the intake duct, and was wondering if that could be the issue. I have read on the on the board here that the FPR has a diaphram in it and can leak. Anyone run into this before, or am I headed in the wrong direction? Any other suggestions?
I read in a manual that when unbolting the brake calipers to replace the rotors, new caliper bolts need to be used, as well as shims. Is the best place to get these at the dealership? Do they really need to be replaced every time? Does the caliper often need to be re-shimmed for proper alignment when doing this?
It also seems the wheel bearings are loose by evidence of the way the wheels wiggle when holding at the 12:00 and 6:00 positions. I am going to pull them apart and service them. They aren't making any noise that I can hear, but I feel it in the steering wheel. I can't find in the maintenance schedule how often this needs to be done. Any recomendations? If someone tells me they need to be done every 7,500 miles, what do you guys do about the caliper bolts? Do you buy them in bulk at Fastenall?
Sorry about the seemingly randomness of the post. Let me know if I should create different posts for each subject in the future or if this is O.K.
Thanks again,
Eric
