i am really trired of this car! brand new dissy, EVERY sensor ,plugs ,wires ,tbi,2 different ecu's and this P.O.S REFUSES TO RUN RIGHT! it will not time right at all! no matter what i do it's either popping thru the exhaust ,or just will not idle at all. i have made sure that 0* is correct on balancer.this is a brand new rebiult jasper motor!W T F? i just don't know what the prob is.i have bought 4 different dissy bcuz e-1 says thats gotta be the problem it ain't !and when it does run it blows blue smoke and smells really bad.i have abouty 3-g invested knowing this i'd rather blow it to he**. then TRY to get my money back,bcuz that ain't gonna happen.

 

just throwing this out, intake leak?
It does sound like timing. I don't know??

 

If you get the time right (and how do you know?) and it isn't running right.... why would you play with the timing again instead of fixing the problem? Have you tested leakdown and coolant pressure? Did you check the cam install? Have you tried timing it by ear? No, better you pass on that one probably if you're already having fits. More info I guess may help.

 

if it is a brand new motor make sure you have the PCV valve hooked up...will help with the blue smoke.

second you are disconnecting the the tan/white or brown/white single wire connector near the blower motor while you are trying to set timing... right

 

yeah, i did the wire thing,and the pcv is hooked up.

 

no intake leak,does it matter where the pvc is hooked up? i noticed mine is in the back of the drivers side valve cover pan,i noticed on here that most of them are in front.

 

well it doesnt really matter where the PCV is on the cover... but you can flip the cover 180* and be like everyone else....

if you have it installed and hooked to the proper place on the TBI then i wouldnt worry to much about the blue smoke yet... sounds like the engine hasnt been run for very long...

as for this jasper engine, did you buy a shortblock and transfer your components over? or a complete engine? swap cams?

what type of dist are you running? the stock type or an aftermarket?

 

its a completely different motor.i have the stock dissy in it .it will start r ight up it just has this popping misfire sound thru the exhaust.

 

yes i got that, it is a different engine but what i was getting at was did you have to do any work to it? like install a cam or anything at all?

How many times have you checked the firing order on this? not enough....

 

Replacement motor companies are notorious for giving you the wrong motor for a specific application. Is it a 305 or a 350? Even more important than that, what cam is in it? For all you know, it could have a flat-tappet, truck motor cam in it, or one that's so far from the stock, TBI specs, it'll never run right with the stock programming. Even though it's a PITA to verify what cam is in there, that's where I'd start looking if you're sure everything else is in spec.

 

it is a 305, it's the one originally from this car.the fellow before was gonna restore the whole car.he had it done b4 i got it. but along came twins ,wedding u all know what that does to the wallet. he said he pulled and sent it to them.

 

Blue smoke=bad. If it blue-smokes with the pcv valve out of the V/C and you've checked the intake manifold gaskets, it's probably the longblock. Do a compression test. If there is something wrong with the longblock, Jasper will exchange it if you don't wait too long. You don't need any paperwork. Even if you didn't buy it, their tag has all the info. If they didn't tag it, the serial number is in their records. You will be surprised. They have a reputation to uphold. They would rather pay freight and swap engines than know that you will be cussing "Jasper Engines" the rest of your life.
Intake manifold gaskets, compression test, call Jasper.
