I want to do a swap from a 91 Blazer that has a digital dash to my 91 Blazer analog dash. Are they compatible? If not, can they be swapped using parts from the digital truck and of course some time. Thanks

Ok, I have a 1998 Buick LeSabre just over 100,000 mi. 3.8 V-6 There is a squealing that seems to increase with speed and driving. Took it in today, mechanic originally thought it was power steering pump - not so. Noise continued when serp belt off. Mech. removed main cap for engine oil filler and it stopped. Starts again upon replacing cap. He checked air filter and hose, found nothing irregular. Replaced pcv valve and for a little bit it was only doing it upon starting for about 2-3 seconds. But later today it is back, though somewhat milder. Any ideas? Thanks. :confused:
