I’m having my mechanic put in new Alliant AC code injectors. Long story short I’m throwing out the POS P.I.S injectors I’ve been trying to live with the last couple years.
I got this picture today while I went out and installed Gearhead tunes while waiting for the new injectors to come in. The firewall has essentially looked the same the last 7 years. However to you more experienced eyes out there, anything catch your eye?
Good eye on the pinched wire, I never caught it until you pointed it out. Would a new under valve cover harness fix it?
The problem I had with the PIS was they ran dirty even after having them out and flow tested by FullForce. They were always smoky no matter who’s tune I ran. Long story short before PIS went belly up, they agreed to rebuild mine to stock speck since the 180/30 set never ran right.
New UVCH harness will work, but a delicate sealing of the existing wires with liquid wire tape and careful placement during install is fixing rather than replacing. Pretend you are a penniless Cuban keeping a '54 Chevy alive. Fix what ya got.
Close it up and see how it runs. Maybe the PIS injectors are OK and just that one little wire sucked.
The pinched wire I see is for the glow plugs not an injector so I doubt thats the problem. What I do see is an aftermarket UVCG some had bad luck with Dormans I still haven't had a problem with one, worth a shot replacing them with an OEM unit.
Looks like bellows to me. This is where you’d look for soot on the stock type up-pipes. The donut seal at the collector eventually leaks and exhaust squeaks by leaving stains on the up-pipes just below the collector.
Baaaaad leaks look like this. These pipes fell out of collector. NOT sealed/tight.
Basically, all of these are leaking by now. Riffraff’s new bellowed up-pipes are the best option for upgrade and should be the only up-pipes you’ll EVER need.
