My son is looking at a 1998 Explorer which has the 4.0L OHV V6 engine (not the SOHC). It looks and runs great except for one thing. When the engine starts there is a squeal that lasts about a second. I've heard this noise on other Fords but have never know the cause. I asked the owner and he said it was the the timing chain tensioner and the noise was common on Explorers. From what I have read in this newsgroup the the timing chain tensioner has been a problem on the SOHC but I have not seen this with the OHC. I'm looking for information on this squealing when the engine starts, how serious it could be, and what it would take to fix it. Thanks, Mark
