Bent some valves huh? Whats up with #1 you have dents way out in the middle of the piston. I would replace that one if I were you. The rest look ok.

 

[unlikely hero]

Looks to me that those were done before I bought the car. I really really don't want to have to change these unless I have to(I'm working outside). Those dents on the inside don't look fresh either. But yea valve was totally broken off in that cylinder. Pisses me off too caus eI just replaced the damn HG.

Get the coolant outta them cylinders you dont want them rustin

#1 looks like a valve head was bouncin around smacking crap here and there whats #1's cylinder wall look like?

 

[unlikely hero]

Walls are good, it just looks like that because the flash didn't go off on that picture. I'll take a better one tommarrow.

If you really dont want to tear down that #1 you will probably be ok leaving it like it is....long as there arent any holes in the piston. Doesnt look like it from the pics. If it was me I would replace it. But like I said you will probably be ok. Up to you.

they'll live.....slap it back together!!!, i've seen alot worse bro'

 

[unlikely hero]

Yea I'm going to slap it back together cause I'm low on cash. If I had it I would def replace the piston but its going to have to wait till summer. When I first pulled the head off I thought there was a hole but nope everythings good. Its just a good reason this summer to do a rebuild w/ some good forged pistons.

Sand down the edges so you don't get hot spots, they should hold up fine.

 

[unlikely hero]

Whats the best way in sanding them down, just normal sand paper. Also anyone know the best place to buy a new autotensioner?

[NA All The Way]

Don'T be cheap go to the dealer for the tensioner.

Oh yeah it's not tommarrow, It's Tomorrow

 

[unlikely hero]

Yea sorry mommy I'm still working on my spelling. I'm don't want to go cheap I just know that you can get the same parts other places for better prices.

For OEM parts Conicelli is one of the best.

Always check the price against your local dealer. You might come out ahead if you don't have to pay shipping.
