- Fri Nov 11, 2011 10:15 pm #281127 hey guys, i fixed my timing issue and new intake mani, iacv cleaned with new screen and o ring. new valve seals and tube seals, i was wondering if i should do another valve adjustment since i fixed the timing belt issue and if tht would help with the loss of power and burning oil under strain??? only thing i can think of is that or piston rings and if its piston rings im selling my coupe bc i dont have the time to fix tht right now.

Uh oh, I had the exact same symptoms on my D15b. Especially when I took off from a red light. A huge cloud of smoke. Turned out to be my piston rings.

EDIT: Sorry if it seems like im thread jacking! It's not my intention! :oops:
