hopefully not detonation!!
Detonation Explained

 

have enough oil in it?

 

are you running premium? is the fuel filter new?

 

exhaust leak, cam chain tensioner, worn chain guides??????? could be several things

 

valve tick? just throwing that out there possible but generally you'd here that at idle.

 

What are you running for manifolds? If your using headers, sometimes the bolts that come with the kit back out and can cause a leak (tick). I was told to use the factory studs with nuts when possible. Also it;s a must to use Ford manifold gaskets.

 

I checked the oil and it was realy low. I am assuming I will need a new engine. My brother in law who is a mechanic is taking a look at it Sunday. He was going to replace the idler pully and camshaft position sensor then.

I have checked the prices of a motor for the GT but was wondering if I have to make many mods if I put a cobra engine it the car.

 

i would check lower intake manifolds, for an exhaust leak or it could maybe be a sticking lifter, worn rocker, ticking sounds can be cause from carbon build up in the motor also. What kind of gas you using?

 

Is this engine pretty much the same as a 99 f-150? My moms truck does the same thing. At idle there is no tick and at around 1500 rpms it starts. I can tell its not an exhaust tick. Definitely an impact sound. My moms mechanic said its normal and I am calling major bullshit. But I know I wont work on the damn thing, no room.

 

I have been using regular gas and there has been gas leaking from undeneath the car when I fill it up. After I start the car and drive it it is fine and it doesnt leak when I dont fill up. My father in law backed into my car by the gas tank about a week ago.

 

Can I put a cobra engine in the car with out any modifications?

 

depends what cobra your talking about, if you want to put a termi engine in, youd need the engine, transmission, ecu, fuel pump, and all that is bolted to the engine. (i think thats it for it.) but if you want to but in an engine from 96-when ever the termi started (i forget what year) then you would need the engine, trans, ecu (would be a good idea, not sure if you NEED it.) and im not sure if you would need a new fuel pump. someone let me know if im missing anything.

 

in the classified threads there is a guy parting out a mach one, and he just got another car to start parting out, you could go ask him bout that engine

 

oh when I bought my Cobalt SS, it was brand new, after about 2k miles I started getting a really annoying ticking sound, I ran some octane boost in the gas and the ticking went away, just a thought

 

ya i have been trying that for a while ticking doesn't go away, i have an exhaust leak, thought for sure it was a lifter, but got it checked out exhaust leak.

 

i dont think youll need a transmission? if you have the WHOLE cobra motor all youll need is the wiring harness i believe. o and ecu

 

at least now its a cheaper job to fix exhaust leak then replaceing lifters

 

lol yeah, thats good news tho!

 

definatly was planning on putting head and other boltons but know have to fix this leak. But better that than lifters lol

 

Had a guy check out the car and he said it needed rocker arms. Brother in law checked the car and said it very well may need a motor but he only works on Chevys. I am taking it to the Ford Dealer ship today to get a definite answer before I put a new motor in.

 

That would be a very good idea
