Two Piece Timing cover
#2
I installed the QTP (sponsor) 2 piece on my GTO. I had a clearance issue with the back of the water pump hitting the front of the upper QTP piece. QTP knew this was a possibility and warned me of it when I bought the cover. I simply took the cover over to a machine shop and had them mill off the part that was interferring. The Guys at QTP are great and took care of me. The new production runs should have this all sorted out.
have not had any leakage issue, nothing in there under oil pressure! will make future cam changes a snap!!

I agree, I have QTP headers and like them very much. I am sure that the cover is of equal quality, the only reason I question it is because it looks like its built around the bigger oil pump and it looks like the pulley would be a problem. What mods have to be done to use the ATI?

George,
Based on the photo on the QTP web site, the bosses at the 3 and 9 o'clock positions where the oil pump is may be the interference points. I would give Barry a call and confirm. If that is the location, and the thickness is there you can likely remove them.

I have the qtp cover and oil pump on my 2004 z06 the cover doesn't leak at all, very well built . i did have a prob where i had to hog the bottom oil pan holes to the left about 1/32, and had to grind a little off the inside edge of the cover where it hit the right edge of the pump. i was using a digital set of calipers to center the oil seal. i think there may be some variables in the holes for the pan. up & down was great, left to right was off, glad i checked it before trying to get bolts started

I did see that photo. Looks great but how ironic would it be that you would have to pull the rack and pulley because your cut in the cover leaks oil. They say it works though
