Rebuilding head

[BLINKY619]

Ok i decided to rebuild my head since i had bent valves and then my valve stems gave up on me.... im looking for valves, valve stems, and valve guides.... can i get a link on were to get them on a budget? thanks

ok so now how would a blown turbo look like... cause when i give my car gas or when its under load it smokes crazy but when its idle it just smokes a little..... also it doesnt smoke immediately it does it when its warmed up... any suggestions?

I can personally vouch for the engine builder valves that are in the link a few posts up. Very nice quality, and I had zero fitment issues. Hope that helps.

you will know when u have a blown turbo not much as your giving it gas.. more when u change gears you def will see a cloud of puff come out it happend twice to me

EDIT** - also remove the intake on the turbo and see if theres any shaft play buy gently seeing if theres any in/out play on the turbine wheel.. its ok to have a little.. very little side to side but not enough where its crashing against the compressor housing

ok well the turbo is off and it has no shaft play at all.. maybe a little tiny bit of side to side but no in and out play... and when i do go through gears there is a puff of blue smoke meaning its oil... but the thing is that the turbo seems fine no oil anywhere just on the turbine when witch looks like its burnt oil, keep in mind that if you see my exhaust ports they are the same color as the turbine wheel= black... so im in between the head and the turbo... but i dont want to dig in and start tearing stuff apart if it wont fix my problem.... also this happened when i gave it a boost leak test witch never reached 15psi...

My guess would be oil was more than likely getting past the stem seals to the combustion chamber. I wouldn't sweat it until the head was back on.

ok well here are some pictures of the turbo and my exhaust ports... ive rebuilt motors before and in the condition mie is.. seems like it is my valve stems.... also when i gave it a leak down test when i tested cylinder #4 it would also leak on cylinder #3 cause i could feel and hear air coming out of it... and visa verse i would do it on the 3rd cylinder and it would leak on cylinder 4

ok so now i found out that in cylinder number 3 i have air coming from my crankcase meaning the rings on that cylinder are done... even tho it doesnt smoke would it be a good idea to just replace them wile im at it?
