I would do a leakdown test. It won't tell everything, but might help you decide if you are going to pull the head. If the valve seats are compressed, then you might also have worn valve guides, which can cause more oil usage or even cause one of the valve guide seals to get knocked out of place.

Re: beaterX project thread
 

I agree with Shane on the leakdown test. At least it gives you something concrete to analyze, I know in our professional lives we have a common consensus that data is king and no smart/intelligent decision can be made without it!

I’m speculating the sparkplug failure event could have messed up a cylinder wall a little, that would be worse case??

Re: beaterX project thread
 

Well the weather outside is frightful, leakdown/compression numbers are trightful, let it go let it go let it go

Evo leakdown results:
1- 50% air from intake & exhaust
2- 50% air from intake & exhaust
3- 20% no leak at all*
4- 50% air from intake &exhaust

Cold compression
110 140 130*110

Walkin in an Evo wonderlaaaaaaaand. :)

Dear Santa....

Re: beaterX project thread
 

:(

Those numbers sadden me

Re: beaterX project thread
 

:( still seemed to make good power for that kind of results if you want to look at the positives

Re: beaterX project thread
 

hell yea! Plus it's 'just' the head. Making plans now for when to get it yanked off, fixed, and re-installed.

Re: beaterX project thread
 

It's a dsm, let r buck :)

Re: beaterX project thread
 

mighty putty??

Re: beaterX project thread
 

Heh! Problem is the car just sounds like shit. It sounds like a diesel until its fully warmed up and oil hot and even then it's not right.

Yes but where to put it, the coolant or the oil? :)

Re: beaterX project thread
 

Low compression = Moar boost = No more problem :)

Re: beaterX project thread
 

Ouch...

Re: beaterX project thread
 

Sucky dude

Re: beaterX project thread
 

2jz swap. Found you a whole engine for under 1k !

Re: beaterX project thread
 

Time for a valve job.

Re: beaterX project thread
 

Re: beaterX project thread
 

Heh, I did that already, see fall dyno day thread :)

Hell yes!

Yea, thats the plan. Gonna get through the holidays and then rip the head off and try to get it fixed asap. The head already has supertech +1mm valves in it, not sure they'd be not good enough...

Re: beaterX project thread
 

Supertechs are nice ones. They have been solid for me, I have the same ones and those have been through two motors on my car. I don't think quality or durability is the problem, at least with the valves, maybe another weak point?

Re: beaterX project thread
 

What springs do you have Murlo?

Re: beaterX project thread
 

Supertechs.

I was going to do Manley's with my build but for whatever reason the Manley ones for the 4b11 are not "manly" and couldn't support the lift on my cams.

edit: sorry for going OT.

Scheides what springs do you have again? Maybe that is your issue? I doubt it though.

Re: beaterX project thread
 

I think his are the same as yours; that was my initial hypothesis.
