Ok i just wanted to ask if on the very first start up, would my pistons bend the valves if the timing wasnt correct? yes or no

if you can plz explain ur answer it would i would really appreciate it

 

Ok im not entireley positive.. But i have a GREAT Mechanical understanding.. So theoretically IF your cars horribly out of time,, then its possible for the piston to meet a valve when it isnt supposed to. BUT pistons have a dome on them,, Its either to A have 1mm clearance for the valve OR hold gas for combustion. BUT i think its very possible it couldve cranked into the valve. you would know it tooo if they were hitting, id say even when cranking for startup. I actually dont think it would even run either.. becuz it'd be sparking at the wrong time. getting gas at the wrong time.. everything would be horrible... It'd toast the engine again.. but if it happens it happens, they messed up SO they have to rebuild it again,, if they don't id sue till i owned the shop.

 

but would that cause the engine not to crank at all? i mean we cant even turn the crank pulley and it does crank but very slowly like if the battery was dead

 

well if your hitting a valve it can't crank.. for example. my friends 300ex atv, he was going down the road and it dropped a valve. instead of locking the engine it chattered the thing into the piston a thousand times, so when he stopped it locked up.. So if a valve was hitting i dont think it'd be able to crank, unless it was just barely meeting,, which i figure if its gonna happen its gonna be worse case scenario where the valve hasnt came down to its full length and the pistons still rising,, that would definetly be a lock up becuz idt a starters powerful enough to crank thru that,, AND i'd guess ud hear a click or something,, id just unhook the tranny or something, but if all else fails theres a junkyard beside my house with tons of 3.8 engines pulled that u can get for 400 bucks. thats why i dont care to blow mine to smitherines. ALSO they are split port 99-04 style so u should see a 50HP increase over ur model stock.

 

Incorrect cam timing can cause the valves to hit the pistons and can stop the motor from cranking.

 

ok at first i thought that they didnt have the timing correct (whcih was the base) thats why i ask this question about it. But just last night i asked them again and they said "yes the base timing is correct, all they had to time was the adjusable one, I was like oh ok.

I thought it was the base timing cuz at first they only told me that they needed to adjust the timing but forgot that there was 2 timin's to be adjusted

 

So wassup? Did they figure it out yet?

 

nope... they are taking the trans down 2day to see if the trans is the problem

 

You can simply turn the engine over with a wrench on the crank before starting it to make sure there is no Piston to valve issues.

 

we already tried to turn the crank pulley with a wrench and it wont budge at all but yet again whenever we crank it the pullies turn very slow

and the piston/valve is not a issue anymore cuz i though they ment that they needed to correct the base timing but instead they just needed to correct the adjustable timing (base timing was correct whenever they started it)

 

If you can't turn the motor by hand then something is wrong inside the motor. Since your an auto you can still turn the motor by hand even in park.
