Icon5 Tapping sound when cold
I've done several searches, and still can't answer my problem so here goes nothing...
A little back ground. I just bought this 2002 GT, Knowing it had a few problems. I got it from a small dealer for a HELL of a price. If I can't fix the 2v then i will continue with my plans of putting a 4v into it. If i can fix the 2v then i'll drive it and keep saving for a 04 cobra swap.
82,555.5 miles.
sohc 4.6
known mods= bbk cold air intake, welded on flows, alarm.
I have been tracking this ticking/tapping sound. So far i tightend the h-pipe to header bolts, and replaced one missing one. Fixed vacuum leak at pass side pcv valve. Pulled passenger side VC to see if anything was noticably wrong. Listening with a stethiscope, the pass side top is where i hear it the most.
Checked spark plugs....
cyl#1 good
#2 loose
#3 time certed already
#4 whole platinum electrode was gone
#5 platinum electrode was severely burned up
#6 loose
#7 loose
#8 good
Got new plugs installed, "autolite ap764 plats" Torqued to 13lb
Idles good now, No codes except for IAC.
Upon starrt up there is a loud tap sound. If i bring up the rpms to 2000 or higher the sound goes away. If i let it idle for 10-15 mins till the coolant temp reaches 200+. The tap will comepletly go away.
I tried dissconecting the COPS 1x1 to see if it changed the tap sound, it did not.
I haven't tried changing the oil yet , it looks good, though. I may try putting some 5w 30 and a new filter on it today. I can't drive the car yet as i'm still waiting to get insurance, inspection,and new tires on it.
Any Ideas???
