In the mean time you ought to remove the egr tubes to prevent further cylinder damage. This was done to my car during install and I haven't had a single problem with the MAC's.

TAKE IT TO THEM, THEY HAVE IT 2 WEEKS CALL AND SAY, NO OIL I SAY NO ****IT. THEY SAY NOT OUR PROBLEM, GET THE POINT. I TOOK IT BACK TO RAMSEY WERE I BOUGHT THE MACS AND THEY SAID THEY HAD NEVER HEARD OF THE HEADERS DOING THAT, AND THERE WAS NO WAY HEADERS WOULD DO THAT.

If you are losing oil now, relpacing the headers alone probably won't fix the problem. Why not try deleting your EGR? And they are obviously lying to you. Any change in air pressure that close to your heads could cause some blow-by. And I don't think I've heard many cases of MAC lts causing 2V motors to grenade...

Have you not heard of any cases or many cases???
After replacing the blown motor with a whole long block from ford 3200.00 ( that way there would be no excuse for the mechanic ) it still blows oil .
I hate to beat a dead horse , but i just wish people could be a little more honest about there product and help us learn our lessons alot cheaper. Heck i wouldve just put the oem headers back on and said the hell with it. The rwhp gain was even worth it.Before headers 352 rwhp after 358 rwhp. i understand it could be the tune but still . Any ways see ya guys.
