comp XE-278 cams and patriot heads...

[98 convertable]

well, Got the engine up and running, and had the cams installed correctly, and the lash adjusters sound like they are loose (ticking). The engine is a houston performance modular 302 forged stroker with dished pistons, and 9:1 compression. Heads are 2001 patriot stage 2. I also noticed my car is burning oil. I might have piston to valve contact. Technically, these cams should operate without piston contact. I called comp cams, and they said if the cams were bought 2 years ago, the base circle could be off. Is there a way to check to see if I have piston to valve contact with out pulling the head? The motor N/A put down 300hp 330TQ at the wheels with a tune from T+J performance in atlanta. Anyone heard of these problems???

do a compression test, if there was piston to valve contact, then your engine will have low compression on all or most cylinders. also do a leakdown test. if there was contact, the valves wont seat properly and air will escape through the intake or exhaust.
