SPent a couple of hours pulling the head after my exam today - at the same time i cleaned the IACV, throttle body and fixed the always faulty FITV!
After

The big thing i noticed from the start was there was carbon everywhere around the intake and exhaust, and this pattern continued right to the pistons and valves.. hmmm only 80k on this engine, it must of been running quote rich IMO. Either that or forced induction burns cleaner! lol

The other disapointing this was the conditoon of the inside of the head. Hopefully u can see from the pics, it had a thin film of caked on oil.. i dunno, it really looks like its supposed to be there.. the texture was consistant thickness also.. just a THIN skin of black covering everything. Less learnt boys n girls, change ur oil regulaily and make sure its good stuff! check out the comparison compare to my valvetrain with almost double the K's!

In the above pics u can see the shony metally bits, those are where i gave it a rub to to get the oil film off..
Anyone got recommendations on if i should attempt to clean this stuff off? or should i just put a nice oil through it? Hints and tips appreciated!
Lastly hear are some pics of the injectors. Everything on this engine just seemed gummy to me, but then again ive only had a little experience with a fwe different engines.

So what do u rekon guys? SHould i just give the head surface a nice clean with some acetone/carby cleaner and try and get everything spik and span, or should i send the head off to the pro's and get it professionaly cleaned up...
Pro's and cons.. will this buildup effect my running? i dont really plan on building her up so i dont know weather to spend the money.

Was lots of fun picking up that engine and especially getting it off the trailer.
Carby Cleaner rocks!!!!!!!!
The difference changing you oil every 5,000.
Once you do your oil, you could run some of that stuff nulon makes for freeing lifters

ALso guys to add, never beleive anything they say at repco. I went in asking for some break in blue for my cam lobes and bearings and they recommended me this stuff called 'Bearing blue' ANyways it turns out this stuff is just for 'reading' and marking stuff on engine internals. Like u can use it to see how well bearing journels are shaped, and if surfaces and consistant and flush after grinding.... im sure if i used this stuff my cam would of worn in incorrectly, and at worst, seized up!!!
Anyways i got this assembly lube made by Nulon - L70 or something! anyone used it before? The guy at Auto Pro said its good and its application chart says engine assembly and anti seizing...
-
yes bearing blue is a bit different , :) and like Jono says, this is why dealers service your car every 5000kms.:)

so when's my buddy who eats xr6 turbo's for breakfast gona b back on d road...? :D :wave: :thumbsup: :p
-
Hahah i can see the blue marker messages me and RT! left on ur cover lol

Ok just got off the phone with Rufes1. The guy they use for there head checking/reconditioning will hot tank/acid dip the head, clean everything up, replace the valve stem seals and make sure everything is well (valves, surface, cracks etc). FOr this im looking at a little under 300. They have to replace valve seals because of the fact that the chemicals they use will errode all the seals.
Now futher talking - taking into consideration head age, im going to give the head to rufes1 to take into work and a mechanic is going to check over it and clean it up with there parts washing machine. If all looks good that will be the extent of the service and i will be boosted by sunday!!

how much did nippon hit you up for frieght??? cos i look into and it was mor fore freight than gasket!
-
gasket cost me 68aud shipped.
same price for freight as gasket - but still cheaper then honda :) this actually wasnt the gasket i asked for.. i was bidding on a felpro.. hmm, gotta check the specs, it feels a bit thicker then my stock..
-
250 for head service he said approx, didnt ring and quote, but yeh a clean and use of a straight edge should be enough
