also, how would i go about checking my heads visibly. HOW can i check the "bad" cracks.

 

also do the other ones look alrite.

thanks alot guys

I would get the head with the first picture checked out, only real way to actually check the whole head for cracks is to get it magnafluxed (local machine shops). The last 3 pics look alright, the single crack betwixt the valves is normal, there is actually a TSB out there. (sum1 want to link it?). That first pic though, if I'm seeing it right there are two cracks there, that could potentially be VERY bad, specially if it goes deep enough to where the metal between the two valves falls out.

GRR, how many times must I post this? Here's a link to my copy of the TSB. http://home.comcast.net/~c.moe/heads.pdf

 

Also on Turbo heads, the crack to be worried about is the one that forms where the exhaust runners meet in the exhaust port. When the crack opens enough, it exposes a water jacket.

yea the first one i am scared about, but the others the crack is kinda thick but it doesnt extend down by the valve , it just stayes on the upper level, in between, (sorry dont know the technical terms) valve seat?

 

anyhoo, thats the story, the first one i fret, but ill get them tested anyway,

 

thanks a bunch,

 

 

 

 

GD, u can post it over and over again, but my comp just wont let me see it. lol

 

cheers,

if your computer won't open it you probably need to install acrobat reader

piss on them cracks, dont worry aobut them.

 

the RX had worse craxks, down to the valve guides, but that didnt stop me from PORTING them and putting over 10000 miles on them thus far.

 

if they do scare you, and if you intend on having the heads looked at, i would suggest staking in the valve seats so they dont fall out.

 

my opinion anyway........
