VALVE RATTLE

Asked by Jul 27, 2011 at 12:13 PM about the 1992 GMC Sierra 1500 C1500 SLE Standard Cab Stepside SB

Question type: Maintenance & Repair

I just had my brother in law repalce the front seal in the transmission & the engine rear main seal.
Now when ever I accelerate, the valves rattle very badly.
What could have caused this just by repalcing a couple of seals?
Thanks.

WELL......here's what happened. The distributor was loose enough to have moved while removing & installing the transmission. I guess it was hitting the firewall, anyway, it moved enought to cause the timing to be off. After a couple of trial & error runs around the block, all is well.
