Got rear ended, then blew my motor. Kill me.

hey bill, your text picture earlier wasnt very clear but now i see the crack! like i said on the phone could be a whole lot worse!!! you got lucky dude. as far as sapper saying you cant reload a tensioner you are wrong!! i did it to derek's car when i put the new head on the drievrside. it wasnt fun, or easy, but i used a tiny allen wrench to hold his piston in while i reinstalled it! well, you found the problem, and know what you need now, its just a waiting game now bill! good luck putting her back together, and i am not doubting sapper's mechanical skills but be dam careful putting the chains back on and it the right spot, or you will have much bigger problems that a cracked sprocket!
 
Ok I was basing my reload judgment on the many import timing chains i've done, the one in particular that comes to mind is on a Honda Odysee..those are "as far as I'm concerned" not reloadable once sprung
 
well its funny because once i removed derek's chain guide i saw the piston pop out fully which i had seen a million times from taking these motors apart. but when i went to put it back on i couldnt squeese the piston in, i thought wtf did i break it? my buddy matt comes over and says oh have fun with that, he had just done it on a cobra a few days earlier when he accidentally put the head back together and swapped the intake and exhaust cams by mistake!! he showed me how to squeeze it and put a pin in it to hold it, it took me 4 tries to finally get it though, the damn pin kept coming out, it does blow!!
 
That's why in a main line shop, we just order another one if that happens..it comes down to..If you don't know what you're doing,leave it alone

It's cheap insurance.

The tensioner piston gets acclimated to a certain position and if allowed to fully extend, it may or may not work properly afterwards, especially with high mileage.

But the general procedure is to fully collapse it and lock it with a pin for installation.
 
Dont new ones come fully collapsed with a pin in them?

Also I read a few different ways to swap the tensioners and figured on the zip-tie method but after staring at my chain...... I dont see how zip tying them will allow me to remove the tensioner and reinstall a new one. Seems like it would make the chain hold a little tighter to the guid in the middle....... oh well, guess I will soon find out. :lol:
 
swap a motor or change a 20 dollar sprocket? hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm

I was just about to PM you. Yeah, dont need the motor which is a plus since I am still broke. :lol:

Already ordered the gear and tensioners for my engine. Will be installing them this week or next weekend. :)


Like my new coaster? :lol:

That part is the one I was talking about earlier. There is a pic in a thread here of one cracked just like yours.
 
I was thinking that remote control looks just like mine, dam that table needs some cleaning!

Umm...and what do you do for "tensioners" that don't rely on pressure to operate??
 
i mean a tensioner that runs on oil pressure....if its mechanical and depening on the vehicle, i dont always replace...

any modular ford engine, that tensioner is getting swapped with a new one, regardless

sorry i wasnt thorough enough for you but in Laser's case, buh bye...cya, a new one would be going in if it was me

but to be even more thorough for you....anything with a timing chain its gonna have a hydraulic tensioner of some sort...right? if not a ratcheting mechanical style right? as for timing belts, thats a totally different story...
 
Yeah as far as I know all timing chains have hydraulic tensioners, there could be one that's ratchet...but I doubt it

as far as Bill getting new tensioners even thou his are tight, I've advised him to replace them...
1) because of mileage
2) it's just plain good sence, since the timing cover is already off.

If it were my car, I would replace the chain as well, just for extra maintainence...but he is on a budget

It's kinda like replacing a clutch, and not replacing the pilot bearing
 
Good to hear it was a relatively easy (and cheap) fix.

btw... gayest thread title ever.
 
lol. I'm not the one getting rear ended and blowing stuff. :lol:

btw, is that a lincoln cobrastar on the SC?
