my 96 obd1 lt1 is knocking out of the passengar side valve cover. im thinking its coming from a lifter.

what should i check to diagnose it better? the ticking sound is coming at higher rpms, and its very evident in fourth gear.

any thoughts?

 

What kind of rockers are you using? They could be hitting the valve cover or may just be loose. Loose rockers will be loud.

 

Check your valve cover. When I installed my LE2 setup, I had the rockers hit the valve covers, so I had to grind a little. But mine were not stock covers either, so just check.

 

well first off, thanks guys.

ive had the engine in for a while maybe 6 months, and now is when i notice the ticking noise worsening. its a stock lt1...heads and all are stock.

i havent checked under the valve covers yet, and im not sure what to look for. im sure ill see one of them out of place or a bit elevated.

other than that...whats teh worst case scenario?

 

Loose rocker / collapsed lifter. Pull valve cover, check all rockers.
