High Knock in my Talon

[LightningGSX]

Sorry I have not had internet access at my house since I got home until about an hour ago. OK I double checked the timing. All marks lined up, and timing is set right around 8-9 BTDC. As far as the SAFC, everything is set to 0 right now because I haven't put in any of the new parts yet. Steve maybe when you get my car, I'll drive the Talon there to pick it up and see if you see anything that I don't if you don't mind taking a peek at it. This is real annoying because I lose a ton of power when this happens. It seems like it's a problem right around the 3-4k range. Even if I am accellerating at a nice normal moderate rate, right when I hit around 3k rpms, it kinda bogs off and on until I'm over 4k and then I'll get most the power back. Thanks again for everyones help.
Your base timing is set to 8-9 Deg's?

It is right around that when I have the timing plug grounded under the hood. Is this not right? What should it be at?

Also I'm looking for some of the revised lifters. Anyone know off the top of their head who has them for a good price?

What kind of oil are you running? If you have stock HLAs and your running mobil 1 they will tick and you might get knock. I run Castrol syntec and its the best oil Ive used against lifter tick. I get no knock and my hlas have 199k on them.

I believe that your timing should be around 7 when the plug isnt grounded. It should be at about 5 when your plug is grounded.

[QUOTE=me612]The knock sensor was not torqued down in any sort of special manner. I just wrenched it on there tight.QUOTE]

You just answered your own question. Knock sensors are very sensitive, follow the procedures and torque specs exactly as stated in a service manual (Helms, Chilton, etc.)

i got my chilton at a checkers. You could also probably find information like this online somewhere. Maybe www.vfaq.com ? OTherwise I'm sure Mike knows. Austen should know as well. I believe mine is right about 7.

My Chiltons and Haynes are in boxes, somewhere, being shipped here from this tiny island in the ocean far far away. No clue when they will be here, and so I have no clue about the torque specs. Anybody know by chance? I just know I wrenched it on real tight. Also to torque it, do you just use one of those O2 sockets with a slot in the side cut out for the wire? Today the car is running much better though. I'm guessing the fuel injectors did something. My knock stays pretty low now but does get up near 20 on occasions, but atleast no more 40 counts.

Alright, you have several problems. Set your timing to 5 BTDC (like the stick under the hood says). The tapping sound could very well be plug wires. Third, set your knock sensor correctly. I believe it is 10 ft-lbs that it is supposed to be set at, that is not very tight at all. If you get it too tight it will be overly sensitive and read too much knock.

[Halon]

Alrighty. I had always thought it was supposed to be 8 BTDC with the plug grounded. But you're saying 5 with the plug grounded, so I will try that. And then once it's ungrounded, it should go to around 7 or so? Anywho, I will do that. Also I will torque the knock sensor less like you said. Again though, what do you guys use to torque it? Just a little O2 type socket? I don't have a way really to use a torque wrench with the sensor because I don't have a socket that will go around it, yet have a gap so that wire has somewhere to hang out, kinda like an O2 socket. And the plug wires have maybe 3k miles on them, but if the first two things you mentioned don't work, then I'll try new wires since they really aren't that much money, and also throw in new plugs. Thanks again for the help.

[Halon]

OK well I readjusted the timing to 5, and I still don't have a way to torque the Sensor in, so I just loosened it and then tightened it snug, not really tight like I had it. The car seemed to perform better the way I had it. I'm getting some 43 counts again now. So annoying. I need to get a way to torque that sensor down, just so I can rule that out.

10 ft/lbs is barely past finger tight. For starters, I'd go finger tight then a tiny turn with the wrench.
