Does anybody have Mantaparts 1148EC in their car?

I have problem with hydraulic tappets breaking and Roller-rockers jump off.

Probably (after examined the damages) does the tip of the tappet break first.
It only happens on the exhaust side.

I use Ferrea valvesprings and retainers, So it´s not a coilbind issue.


I´m starting to believe that i´ve been hustled ones again by s**thead Tim.

how long did it take for you to actully GET your cams.... just curious.

Mantapart site claims you need better springs.

What kind of car is that...your speedster, I like it a lot.

About 8 month and he still owes me parts that i´ve paid for (300$).
I ordered in 2004 and i will never ever recommend this crap company to anyone.
I will badmouth them whenever i get a chance

Ordered uprated springs, But he never sent them. Had to get them from Ferrea instead.

It´s my race-Speedster.
