Top end rebuild/refresh on my H22A7 EK!

[Turkish]

Thought I'd show a few pics of what I've been doing in my spare time for the last month or so!

Basically, I bought my EK and was really happy with it however after a few days, it started to run like an absolute dog! It smoked a little bit upon purchase, and I thought nothing of it really but by the fourth day it was billowing out and also VTEC was intermittent as well. Done a compression test and got some piss poor results so decided to take it off the road and rebuild it.

Here is the work that has been done to the head...
- Cleaned up first with a dry blaster, then a wet blaster & then skimmed
- New valve seats
- New valve guides
- New valve stem seals
- New valve springs
- New retainers
- Valves refaced and carefully lapped in to match the new seats

All work has been done by myself with help on the trickier bits by my next door neighbour

New parts awaiting to be fitted with the re-assembly (DNR are doing this not me!)
- Timing belt and tensioners
- Head gasket & all other top end gaskets
- Water pump
- Thermostat
- Sump (that isnt scuffed and dented to oblivion like the one currently fitted!)
- All other service items (filters, fluids, plugs etc)

I'll let the pics do the rest of the talking...

Good work.are you sure its just the head at fault. As the ringss could be partly to blame also

 

[Gav-EK9]

nice work mate, the engine will thank you for it

 

[Jimbo]

Good work dude, as EG6-r said, you should have looked at the oil control rings and piston rings while the head is or was off! Blue smoke whilst in VTEC 90% off the time is top end related I.e valve stem seals, valve guides but smoke before and under load is rings or ovulated bores!

looks class a nice rebuild mate will keep my eyes peeled on this thread

 

[CAL]

nice work. was a good read.

 

[Topher-EK9]

good work... such a shame this happened so soon after new ownership...

 

[Turkish]

Yes, bores were checked whilst it was off and only some very minor marks on cylinder four, so minor you cant even feel them with your fingernail. All the other bores were spot on! It was black smoke and only doing it in VTEC.

Should be fine, but if its still playing silly buggers then I will know what needs to be replaced as it wont be anything head related

nice work

imo you should of changed the rings as well since you were that far down, just in case...

I know, however imo it's a lot more work even though I had already stripped it that far! Fingers crossed

Back on the car down at DNR, it's getting there!

Should of cleaned up the block as well... bit of a mismatch haha!

Good job and hopefully the block is in good condition still.
