That is great, glad you are enjoying it so much, I also enjoy mine! The problem was Linimar not boring the seats concentrically in the heads, this is what created the premature wear problem. If you are not seeing any oil use or blue smoke upon start up, then there is a good chance you may have...
Have not been on here in a long time, just saw your post. Good for you great feedback on your Z, I did not catch the year? In regard to the Blackstone reports I use them myself, however with only 3,000 miles on my 2011 Z07 (which I bought new), with previous good Blackstone reports, my valve...
Hi Folks:
The Corvette pictured in the banner heading is an Inferno Orange Z06/Z07 with the CFZ option, not a Carbon. Notice it has a black painted roof and the side view mirrors are body color, also the rims are grey. A Carbon edition would have a body color painted roof with black painted...
Well, have not been on here for quite a while. Just thought I would share my build story. My 2011 Z06/Z07 with 3,027 miles on it had bad guides; three of the intakes were so bad they were moving back and forth with the springs still on. Anyway I went with AHP heads and the Moldstar 90 guides...
Tuna, with all due respect, Hib's statement caught me off guard a little bit, I am not sure how one could make a statement that a car was built outside the problem range and the issue has been "fixed". The issue appears to have been poor machining by the supplier Linmar and there has not ever...
Tuna, with all due respect and deference, your experience would not preclude your LS7 from the problem. I would recommend you "wiggle" your valves, especially the exhaust side. 15K miles is no marker for the problem, it has been identified by many after 15K miles.
All LS7 motors are suspect in regard to the valve guide issue due to potential machining errors from Chevys sub that supplied the heads. The only way to tell you have a problem is to either remove the heads and measure the guides or perform a head in place "wiggle test" to determine if there is...
I know about the exhaust Hib, I followed your posts about the swap you did on your car...you helped settle a dispute on the "other" Forum about the 2011's having more HP due to the exhaust and the sound is amazing...I love the decel, thanks! :thumb
Hib:
I know this is an old thread, but thanks for posting the link and the article is fantastic...I just re-read it and fell in love with my Z06 all over again...what an amazing engineering accomplishment. :thumb
I tend to agree, I have been monitoring C5 wholesale pricing over the past three years and it continues to drop annually, however interestingly enough the retail pricing has remained relatively stable for low mileage vettes. The dealers are making much more profit on the C5's now than they were...
