How much would it cost to fully rebuild my f22?

[b3nsonx]

So after changing my valve cover and spark plug gaskets, i find that the lower end of the sparkplug still has oil, under the compression ring. (New sparkplugs too). I'm told that it may be either...cracked head (unlikely), bad valve guides, or valve seals. I will be doing a compression check on my car tomorrow and then i will decide whether or not to rebuild at this time.

But for now, i just want to get a rough estimate for how much it would cost me.

f22a1
Port and polish
blue printing
bisimoto stage 1 camshaft
rebalanced crankshaft
h23 intake manifold
h23 throttle body
Not sure what else, maybe you guys can help me out.

Going for 150 whp at 87 octane, kinda like Hondafan's red project
What's a good price for this?

For 150whp, you can use your F22 block as long as it is in good shape as-is, no extra work. If you want you can install new rings & hone cylinders to restore the block in a sense, but at that rate you may as well install new rod bearings minimal. Mains should be fine, unless you've done some damage there in it's lifetime.

For rest of info, refer to the stick I made:

well i was thinking that since i will be taking out the engine and taking it apart, might as well get all the things done, right?

btw, my engine has 193k miles on it.

Taking out engine is one thing. However, why do you have to take engine apart? If nothing is wrong with the block, work on bolt-ons as I did with my red project. Otherwise, you're wasting money, you can get 150whp without touching the block as I proved.

If you find out the rings are not sealing, then just install new rings on the pistons and check the bearings while you're there. If they are fine, leave them. Otherwise you may need to replace rod bearings and mains should be fine (unless you're engine has had bad history). For 150 whp, doing anymore than this is a waste of money.

i did my compression test today and found out that my compression for every cylinder is between 125-130. The minimum spec is 135, so im kinda below.
But wont working on the block also provide more reliability?

Not necessarily. If you have an already good block, there is no point in tapping into it and it costs money like anything does to upgrade. I'm keeping things simple and budget-oriented for you. People get way to ahead of themselves and don't realize future expenses, think reality not dreamworld. I know what it takes, I've been there on a milder build and more extreme FULL engine build. I don't care what anyone says, it is not cheap and I'm picky to boot so I replaced just about everything.

For your goals, you do need a decent block. A compression check is not a good way to tell a motor's health. You could be losing compression through bad valve seal and just need a reconditioned head, which you should do anyhow and will be done if you get a ported head like I mentioned.

So do a leakdown test, determine if you're block is in good health (minimal piston ring oil blowby, heard through the crankcase breather or PCV ports in valve cover). Assuming that is fine, leave your block alone.

A compression test just tells you if your motor is not building up full pressure, which can be attributed to many components and it does not break it down for you. However, a leakdown gives you better status on the health of your motor and where the leaks are coming from so you can attend to them in your build/project and potentially get maximum output of this motor with the mods you're considering.

I dunno if it bolts up to the CB chassis w/o extra work but if ur gonna tear down ur F22 u might as well get a low mileage F23A, and throw the VTEC head in the garbage. Higher compression, more displacement, much lower cost & gains than rebuilding an F22 back to stock compression/displacement

[RiceKillinSi]

Just to clarify did you replace the upper or lower spark plug tube seals. It sound like you only replaced the upper seals. It might be the lower seals that are leaking. Check out this thread about changing the lower seals.

It is a little more involved, but if you are mechanicaly inclined then it sould be easy.

[b3nsonx]

yea, this topic still confuses me, im pretty sure i replaced only the upper seals because someone told me that in the valve cover gasket kit at the dealership, they only give you the upper seals.
So i think i only replaced the upper seals.

what do you guys think about this kit?
anyone here ever try it out?
