So awhile back when my head gasket blew on my 86 toyota pickup 4x4. I was gonna have some work done to the head but the machinist found a crack in the head basically saying i need a new one, so i reached out to sunwest automotive cause they said they had new cylinder head castings. Wasnt until recently that 22re performance told me some new castings have their own set of problems like the main oil drain hole in the back of the head not being large enough to let oil drain back into the pan.

Im just wondering if anyone knows more about this or if i should be worried about that. Block is also from them but the head has bout 12k on it while the bottom end has bout 50k, head is straight, pressure testing was good, and had better valves put in it cause the ends of the valves werent that great, had zimmerman auto racing source some stock sized valves and had him install them.

Any input would be helpful so i can plan for the worst

 

12k what's, kind of rhetorical, if it hasn't been showing signs of oil starvation I'm not sure why the question at this point.

Call LCE get more details, contact Nick at Sunwest and get more details on what parts they are or were using once you have more data from LCE..

 

Called lc waiting for a call back, called sunwest though and said there heads are from itm, which 22re performance says everything is absolute garbage.

 

I know nothing about this brand head, or of any oil drain issues, but I have personally seen chinese head castings where the oil dams that are supposed to provide cam lobe lubrication were incomplete; and some not tall enough to provide an oil pool that could wet the cam lobes, resulting in very rapid cam lobe wiping and destruction of cam and rocker arms.

I have heard good things about the Spanish made castings, but those are expensive. IMO:: Best thing to do is find an uncorroded genuine Toyota casting and have it reworked.

 

Well there is someone I expect could put up some imperical data of what dimensions are sub par.

Just saying "it's Chinese trash" doesn't provide the needed feedback to the manufacturer, shame on you (22reperformance).

But I digress..

Yeah a Toyota OEM head is always preferable since they were not casting parts for multiple brands and models like the aftermarket people like itm (which from what I recall are produced in a half dozen factories in multiple countries)

 

Woah, woah, woah!

Where in this thread did 22RE Performance say that the ITM heads were just "Chinese trash"? They said they were garbage, according to the Thread Starter. The Thread Starter did not go into further detail. I am sure 22RE Performance knows what the problems are, where they are, and would be willing to talk about these issues with you.

 

Sorry for the late reply yall, but anyhow, dont recall 22reperformance saying anything about the head being from China, just stated the oil drain hole to the pan being too small and the metal being pretty soft and not good for longevity. Doing a quick search on ITM there based in Carson California but didnt find anything about where they get their parts from.

 

This is a common discussion and concern among the 22r/re community. I spoke with 22re performance a few weeks back about the ITM head issue, and many times over the years. The fact is, that nearly ALL 22r/re/ret builders (yes, even LC) utilize ITM heads at one time or another. They get them where they can and do quality control/checks inspections.. ITM sources head castings from various manufacturers themselves, some are up to snuff, some definitely are not.. it depends on the batch and where ITM received the part from.. when, what time etc. They’re not ALWAYS garbage. But, they can be. So, the best advice I utilize is 1) doing your own sourcing and quality control, or 2) trust an experienced and HONEST builder to do the spec checks and quality control, which 22re performance is famous for. I’m running an ITM head from Sunwest and have been for the last 3 years. The head is fine. The 272 cam is another story.. soon to be investigated further.

 

Well this is an interesting thread. I put an lce head on my motor about 10k miles ago, it is showing numerous signs of premature valve wear, which could also be due to a few thousand miles running fairly lean, also this:

So have plans on a 22reperformance build if those start happening again. mostly impressed with LCE's header, have bought other stuff from them (alternator, short shift kit) that was total garbage.

 

I tried the LCE header a few years back. I honestly noticed less torque with it and so removed and sold it. Of course, I’m just going by feel and not data, but the limiting factor on the 22re motor is not the exhaust manifold/down pipe system. And of course, this is also dependent on the specific motor (porting, volume, condition, cat/no cat, muffler, pipe diameter, etc). Back pressure is required to produce torque. The header was noticeable at higher freeway speeds where horse power is in play, but still, I was not impressed with the header‘s performance. They are gorgeously designed and engineered/fabricated, but I’ve often wondered how much torque gain would be observed with smaller header pipes on the system, preserving back pressure.

For the money, my favorite part LCE produces is the big bore throttle body. Then again, realizing the improvement is dependent on tbody-upper plenum match porting. That made a good difference for me.

 

I am in Phx area...have an orig used 22re head, never cut or touched. I might still have oe valves. Clean like new. Head was given to me 10-15 yrs ago. Been on the shelf long time. Would sell cheap....no use for it. My 94 has orig head, at 310,000mi!! Karter9907@yahoo gilbert,Az

 

Well jjswenn, i guess time will tell, hopefully like u said i got a good batch, ill just keep an eye on it when i reseal my valve cover, interesting comment on header though, i run a headman header but ive had it for so long i dont even recall how it ran with the regular manifold nor exhaust i replaced both. Oldbluemidnight, i ran into the same issue, you prob have some cheap valves that are made of soft material, i found mine pitting at just 12k, so i replaced them with better ones, hopefully my cam isnt soft too. And karter 9907 id be interested in that but i do have a 22r not an re. So is there a difference between a 22r and re head?
