Have you checked your car to see if you have had PTV?
I know of cars with VT Stg I, VT Stg II, Comp 262AH( PI ), Comp 270AH( PI ) cams all have PTV issues. Some cases the PTV showed up right away and damaged the engine. Some have gotten a few thousand miles and then the PTV took out the engine. Others were unlucky to pull their heads for headswaps, only to find PTV on the pistons when using these cams.
What causes PTV is IMPROPER CAM installs. I am getting tired of this crap of people telling others that all they have to do is remove the valve covers and swap cams. I don't care who that person is, that is NOT the way to install performance cams.
The stock 2V cam gears have a wide tolerance in them. For a mild cam like the stock cam is, there won't be any problems, however you won't know for sure with a more aggressive cam. Unless you have degreed the cams in, you don't ****ing know if they are going to cause problems or not. You now know why so many have lost engines or had extra expences due to crappy cam installs. Also, you will get the best results by a degreed in cam. Degreeing in a cam requires the front cover to be pulled.
If you want to install these cams in your that way that is fine. Don't come back a crying when your car is broken. This is going to be my last warning regarding cam installs. If people want to do the way as suggested by hotmustang331, when I see more threads of PTV taking out engines and such, this is going to be my reply.
You was warned!
