420A Timing Belt Issues HELP

[Baldwinnn]

Okay so guys, I have a 1997 Eclipse GS, 2.0 DOHC Non-turbo, and I know the timing belt jumped, it tends to die if I drive it over a certain distance, and when it dies it will not start for a bit, and as strange as it sounds I have to redo the firing order sometimes just to get it so start back. now I looked at the belt and i can't see any bad teeth or don't feel any slack, but it's very clear the cam gears are not lined up and I know it is an interference engine, I just wanted to know the possible damage that can come with it, and how hard of a replacement it is, or how much someone will charge. please and thank you guys

i jumped two teeth on my 4g63t and it mangled 12 out of the 16 valves and the other 4 were bent very bad. do a compression test, then a cylinder leakdown test. can almost garuntee your head and pistions are going to look mangled if you've been driving it with a skipped tooth. shocked it still runs being a tooth out

 

[Baldwinnn]

i can go out there right now and it will fire right up, i just hope it's nothing major, how much did all that cost you with the valves?

 

[northernawd]

i did a full rebuild. but i did contact Strictly Import Motorsports and they are currently building me a long block. i believe the stage one build is around 3 grand

 

[Baldwinnn]

is it possible to just get new valves and such?

It could be possibly you skipped a tooth on the intake cam, and it is opening too late?
I had this happen when i was putting my timing belt back on, i may have gotten lucky, but all that happened was it would bog down, and run rich as hell. valves/pistons are in ok shape minus the carbon buildup from the too rich mixture.

Broken/slipped timing belt

Installing/replacing a timing belt IDK if this one will help much unless your engine is the 6bolt.

Base Timing

 

[northernawd]

it is possible, but if you look into those suggested links you'l see that the valves can break off and damage the cylinder walls and pistons as well.

 

[Baldwinnn]

well I bought the car on Feb. 8th, and I can tell the people before did not maintain it, and it has lost a bit of power since it skipped, and it seems to bog a little

Are you positive that you are aligning all 3 timing locations? Crank and both cams? Doesn't sound like timing. If timing is off it will be a consistent problem. It will not come and go with driving.

 

[Baldwinnn]

well i can take off the inspection cover and i can see that the gears are off, they don't line up at all

Goto VFAQ Site - Visual Frequently Answered Questions and check on how to redo the belt timing on that 420A motor.

Taking the covers off and pulling that main pulley is a total PITA since one needs the three clawed puller to get that front pulley off.

Might as well throw on a new belt while you got everything taken off.

i forgot to mention it was a 5 speed not sure if it matters or not, and i plan on it, i was gonna put a new water pump, and new tensionrs while i was at it, kinda off topic, but what could make a speedometer, odometer, and cruise control not work other than the speed sensor,
