ran the egnine with no header, no ticking.....might be masked by exhaust

Vid below; for some reason no flamage on the photobucket version....you can see it on my camera

^^^ haha..that's crazy. anyways, if you can see the hole, it will definitely tick. it doesn't take much.

Good deal Lee! I'll bet that's the tick.

[LGAFF]

Still have a tick, not sure what the issue is at this point.

Got a stethoscope ?

[LGAFF]

yes....checked the DS cam cover has more lifter noise than the PS cam cover but nothing on par with the tick I hear. Will check more today....

LAstI check with the Tech 1 no knock retard, so unlikely a rod or crank bearing


PS: Dom was wondering if you might be able to burn a chip for the 92? Have the new chip

Lee,

We can use the last calibration I have before doing the heads and cam on this motor. Our motors were pretty close at that point in terms of mods. Having fixed your knock retard issue, maybe now you can take advantage of the changes. Give me a shout when you want to get that.

Took the car out, ran the hell out of it.....5-6 7500rpm runs. no knock counts at all. Then took it up to 7500 and held it 5-6 seconds.....then I came up to a stop sign..no tick. Cruised on the highway back to town, pulled in a parking lot, faint tick. Then parked it, came out and tick was noticeable.....then drive it an tick went away again.

Pretty sure this is an exhaust issue....maybe there is a reason I got the headers for $500.00

Lets hope thats it for the drama, car feels strong; we'll soon see if the seat of pants dyno is accurate....

as an example of how easily you can hear the smallest airflow, blow across the tube to test it out. You will find a small leak this way.

OPen tube...Great tip! Especially for finding an exhaust leak.

drove the car 320 miles the last 2 days, runs great....biggest issue is that these tires will never hook; gun it from a roll and the car kicks alittle sideways and burns them up....hope the dyno numbers match the seat of pants o meter.


BLMs at cruise are 116 and 128 at WOT
