did the intakes. . . now the motor is Fu@%$!!
Hey guys. . . I bought my 95 GT from an older girl last fall and I was having some problems with it spark knocking, checked the timing and it was advanced 10*. Checked the fuel press. it was around 38psi. Took the cats off. it wouldnt do it all the time, but every once in a while. . . anyways i parked it at a guys shop for the winter and dropped off a bunch of parts, he noticed the harmonic balancer was shot, rubber hanging out the back side, so thats prob. why it was pinging, becuase we wernt getting the right timing due to the balancer being spun.
Its a stock 95 GT 5 speed. 190kms on it. Over the winter, he put on: new balancer, underdrive pulleys, bbk headers, Typhoon upper+lower intake, 70mm throttle body, CAI, removed smog pump and egr, catless X-pipe, and 3.73's. Anyways i went and picked it up yesterday. drove it back to my house which is about 10-15kms. shut it off for about 3 mins. Got back in because i wanted to take it for a spin down the highway, went to start it and it turned over very hard, thought maybe the batt. was low, but it fired up. Went down the highway (had a problem but ill post that in a min) came back into town, was idling through town in 1st and crammed on her and it didnt even break loose, had $hit all for power, so i pulled into my buddies yard and at idle my oil pressure gauge (stock gauge) dropped right off!! gave it a little fuel and it came back up, but as soon as i let off the fuel to idle i lost pressure, popped the hood and she was knocking. . .
Last fall it would act up a lot, it would work really well, then sometimes it was bawlless. . . we cleaned the maf no luck. . . thought it may have been something to do with it spark knocking.
anyways guys, I have no idead why this happened, maybe it was ready to go last year before i put it up for the winter. . .
I brought it back to the guy that did the work on it, he said it sounds like a rod bearing, you can hear it knock when you give it a little fuel at idle, (floating).
It always used castrol 10w30 and this time after the intake etc. was changed it was started and idled for a while, then shut off and changed the oil, but instead of normal castrol, we used castrol syntec 10w30 (synthetic). . . i dont think this would be the culprit though. . .
last night i was looking under the hood at the pulley diagram on the fan shroud plastic and noticed that how the belt is routed now is making the water pump spin backwards. . . but i didnt notice it over heating when i took it on a 10 min run down the highway. . . but it may have, maybe thats why it started hard, maybe it was really hot. . . i dont this this would screw the rod bearing if it did heat up though? but its not spark knocking anymore. . .
any ideas guys?
P.S. When i took it on the highway, i turned er up pretty good and at around 180km/h i got a real bad fast vibration that kicked it out of gear. pulled over and it stoped, I had a vibration in it last year at high speeds i noticed, you can feel it in the shifter, but anyways i pulled back on and it shifts 100%, Could this be a bad U-joint, becuase if i had a vib last year with 2.73s and now i would have 3.73's the DS would be spinning that much faster. . . when i pulled it out of my garage this morning to turn it around there is tranny fluid on the floor

the car has 199,xxx kms on it. The spark knocking seems to be gone now. In New Brunswick we dont have any Sunoco stations and the highest octane we can get is 91. . . supreme, thats what i run. it seems to run good and not missing but once i ran it down the highway and back (20-25kms) driving through town it seemed to have lost a lot of power but not skipping. . . i am gonna pull the motor but i wanna find out what the vibration is first, if it is just a u-joint then thats fine cuz im gettin a new alum. shaft anyways. but if the tranny is done, I might as well change that when i have the motor out. . .
i didnt drive it after i noticed the oil pressure and knocking. . . today i started it to turn it around in the garage so i could work on it. . . oil pressure was fine. . . but it was cold, so.
the tranny is a 5 spd.
the timing was set to 14* with spout out. after it was all back together.
When i picked the car up yesterday it worked awesome all the way home (10miles)
then i took it on the highway it worked good except the vibration. got back into town and it just wasnt working right there was a big loss in power, thats when i pulled into my friends yard and noticed at idle no oil pressure. the needle falls right off. . . below the low mark, as if the gauge wasnt even working, but if you would bring it up to say 1500rpm the needle would come back up. . . then i noticed the knockin when giving it just a little fuel from idle.
i found another engine today, 306 short block, forged flat tops and a mild cam. It has less then 1000 kms on it for $800 but it has been sitting in a garage wrapped up for a year and a half, so that makes me iffy.

Wow.......
I had about the same luck as you when I first got my 94!
I had bad vibrations, my balancer was spun, SOME mornings it wouldn't start I had to boost it and roll it over and over for 5 mins straight but once it fired up it would start all day with no problems, I had MAF problems, etc....
Thats when I had enough!! then I pulled every stock part out and spent THOUSANDS of dollars and replaced EVERYTHING fuel tank, exernal pumps, lines, motor, LOTS MORE!
As for your Vibration problems, you could borrow a buddies DS and see if you still have problems rather then spend money into new U-Joints for nothing.
If you plan on getting a Aluminum DS this might be a kick in the butt to get one now lol.
What kind of Balancer was put on your engine as a replacement? New, Used? Factory? is it a 2 piece?
Who did your gear swap? Did you ever think maybe just maybe you bent a AXLE? this is very possibly...
If your belt was routed in the wrong direction this would def. cause a over heating problem!
Dont always rely on your factory gauges lol
I have seen/experienced knocking engines from switching from reg motor oil too a full synthetic motor oil this to me is a VERY big NO NO! Ill never do it again or ever recommend someone switching to synthetic or visa versa!

buy the motor put a new oil pump on it check your front seal in tranny when you have engine pulled it sounds like the pick up is half blocked or no crank case ventalion or bad sending unit put a windage tray on new engine it helps if your rear end was not rebuilt just changed it may be the cause of it do you hear a growl or whine.Check your flywheel for cracks u-joints, get tires balanced if it gets worse the faster you go cheap and the cause of more wierd shakes than dairy queen.

well, last year i had the same vibration at high speeds, but this year is worse, but that would be the result of going from 2.73 to 3.73's, everything would be turning faster. . .
The car was lady driven and before that an older guy so it has probably never been really ran. . .
anyways this other block has less then 1000kms on it, new flat top forged pistons, b or x cam (he cant remember. he built it for a guy and he couldnt afford to pay for it) new oil pump and water pump on it, no intakes or heads. . . but the engine has been stored in his garage for around 2 years, so that makes me weary. . . should be okay though i hope as it WAS indoors.

not sure if this could be the cause, you did say you changed the oil, But after i stored my jeep all last spring->fall, first trip out before the first snow, i started down the road, and oil pressure dropped to 0, ended up that the filter collapsed and wasn't allowing much oil through. Perhaps if it starved the engine already, it fubarred everything already.
not sure if you live right by the ocean, but if the new engine is headless etc. could salty air have gotten inside or is it sealed well?

stang illusions the balancer that was put on was brand new, i got it from rockauto.com, we just got another snow storm here, so i'm waiting for that to go away so i can bring it to my old mans and work on it. . . i havent even looked at the thing, pretty pissed off and depressed about the whole thing. . . on top of all that i got laid off in december and wont be back to work for another month at least. . . and i just handed the guy $550 for labour for doing everything, drove the car for like 10-20mins and now all this. FACK!!
aw well.
aw well.

question: When he changed the intake, it's quite possible coolant got down into the oil right? and after he was all done he started the car and let it run for a few minutes, then he changed the oil. . . could that have maybe screwed it. . .

i looked underneath last night and a the tranny fluid was all over the crossmember/tranny mount. . . couldnt see where it was coming from though, didnt look to be coming out of the tail or anything, was gonna pull the crossmember off but my dad showed up and we went sleddin. . . anyways, im taking off to montreal today, gonna give my ol man a hand, gotta bring a load of dirt there. . . guess ill find out more in couple days. later
