if the a/c belt and the alternator belt gets damaged or literally fly off week after a timing belt change is done can that break some valves? dose it suggests a wrong installation.. My car has vary low power after a had the timing belt change but especially a week later that those other belts went off (a/c & alternator. and i dont know what else.. help please
i just bought a 96 eagle talon with a 4g63 that someone took the head off and has everything apart but has all new parts i need to put it back together.. does anyone have instructions or anything on how to do it.. do i have to pull the motor or can i leave it in the car?
@countryboyG you could do with the engine inside but it would be easier to throw it on a engine stand and put her back together, also remember torque specs and PM me if you really going to get your hands dirty
@OEFarredondo I did it about 3 months ago and the car runs now i drive it all over but.. like when its in park or even when your driving it it seems like if you push the gas down while its in park it takes a while to rev up.. i know the biss screw is off because if i put it in the right spot the motor revvs up to about 1500 - 2000 rpm and if i try to adjust the butterfly on the throttle body then the throttle sticks.. soo i have the biss screw to where the idles about 900 know how to fix this?
@miragejuan Yes, there is. Look at expertvillage for timing belt/water pump replacement. Guy in video is doing a 2.4edz Stratus but its the same steps as 420a.
Early 1990's Mazdas and Mitsubishis were over complicated to the point of not being reliable. Hence the customer satisfaction stuff and updated 100mm tensioners etc. Imagine if OBDII wasn't instated how hard reading codes would be for these cars by now..... SHEESH!
To be a little more specific than the ihart was. both engines have there differences the 6 bolt being the better of the two. 6 and 7 bolt a just designations based on the amount of bolts that hold the flywheel to the crankshaft. the 6 bolt has beefier internals and stock for stock it can hold more power than the 7 bolt can.
I have a '90 AWD Talon with a '91 motor and I can't seem to get it right. there seems to always be a loose spot on the timing belt as the tensioner pully pushes the auto tensioner down and then it pops back up. also there seems to be a clicking noise by the cams, can anyone help me with my problems?

you wont bend a valve from a worn T belt unless it snaps. Best way to check for a bent valve without taking anything apart is to do a compression check. 120PSI is the minimum service limit for the 4g63 engine. 180psi is max.
So with the compressions I got, most likely I won't be needing a Total Engine Overhaul right? Could just top overhaul do the trick? I am getting blue smoke by the way.
Well, Blue smoke is oil burning and that would explain the carbon build up in the cylinder. Is it burning oil on start up that clears up after a bit of driving or does it continue to smoke? Also what exact model do you drive and many miles does it have? If you are only smoking for a while after start up than it is probably valve stem seals/guides. However if it continues to smoke as long as it is running chances are it is worn rings/cylinder walls.
It continues to smoke. It used to occur only at 4500rpm and above. But now it smokes continuously. With the 130psi lowest compression pressure I got, you think I need to sleeve up the cylinders? Or can it just be solved by replacing just the rings. Thanks a lot. BTW, I have the Philippine local Galant GTI with the 6-bolt 4G63 DOHC Non-turbo. Does these engines usually need rebuilding of cylinder after 100K km mileage at normal use?
I cant really tell you for sure. You would have to have the cylinders checked to make sure they are in spec. They may or may not be damaged. If they are out of spec you will have to get them bored over and buy new pistons as well as rings. If they are in spec you will have to have them honed and get new rings. If you do not hone the cylinders before you replace the rings, the new rings will not seat and you will have the same problem.
If i were you I would go ahead and do an overhaul. You can get a topline rebuild kit (which are pretty decent for the price. Slowboy racing uses them on some of there builds) for about $350 US After that it comes down to machine shop costs which are not that bad for 4 cylinder engines.
You can find the topline rebuild kits on ebay all day every day just about. Theres a guy by the user name of mopparts that sells them for a really good price. I'v seen people run 400hp with one of these kits and as I stated slowboy racing uses them on some of their engines.
too bad all the cars I really wanted to own since I was a kid....are too old or impractical for me to own as I don't have much space. IE: 55 plymouth, 62 merc comet, 49/50 ford, Rambler Marlin, oh well
QUESTION: why did auto manufacturers change over to BELTS and abandon the older style steel timing chains.? A steel chain can last the life of the car.
quieter running,but mainly so dealers can charge to replace them at extorsionate prices.however, i have had to replace timing chains on quite new cars as they stretch.
Possibly because I am not racing my cars ....just regular passenger car use, but I have never had to replace a timing "chain" on all the cars I have owned....62 chrysler, 65 chevy, 77 buick, 86 pontiac and 93 olds (my present car). Possibly because I drive like a old man.
its mainly very new cars. i work as a mechanic and have replaced many chains for poor running + engine management light faults,especialy new shape nissan micras(other makes as well), this has become a common problem recently

wat does it mean to have a 6 bolt or 7 bolt
martinez197 2 years ago
It refers to the amount of bolts on the end of the crankshaft

Negative. They actually stopped the 6 bolt motors in May of 92. Some 92's have 6's, some 7's. Stupid 7 bolts getting crank-walk and shit...

That's not the purpose of the video, it's hot-to change the timing belt. You'd know right away if the valves had been bent.

how do u knw f a velve is bent from tha cambelt just being worn
raupadonga 3 years ago
you wont bend a valve from a worn T belt unless it snaps. Best way to check for a bent valve without taking anything apart is to do a compression check. 120PSI is the minimum service limit for the 4g63 engine. 180psi is max.
Master7770 2 years ago
If you have a bent valve you will have very low compression. So if you are out of spec you will know something is wrong. Be it rings or valves.
Master7770 2 years ago
@Master7770
Hi, I got around 230+psi, 130, 140, 145 after compression test. What does the very high compression on cyl4 mean?
p00000y 2 years ago
Well high compression in a cingle cylinder is most often caused by excessive carbon buildup. I would try a seafoam treatment and then check it again.
