Info on v3 Heads please.
 

Car is a v3 STI
I'm after some info on these heads please.
Do the buckets have the shims attached or are they separate shims?
Has anyone ever replace the buckets with the engine in the car or would you know if this is even possible?

Cheers
Rich

Have a read of my build thread lol


Exact same issue and just whip the engine out. Saves much ball ache

lol started reading it then got diverted with all the cr@p i'm going through with my car ffs.
Going to sit down tonight and read your build thread from start to end tonight!
sounds like you have been through a fair bit with your car.

Cheers for the advice,looks like i will be investing in a hoist and engine stand.
Got a mate whose a mechanic,he knows feck all about these cars really(he is good tho) He said he would just take one head off and sort it that way lol :nono:

You will really struggle to get a head off with the engine in place!

It is possible to check the tolerances with engine in car. Difficult but I did it on mine.

How ever removing the cam etc was a nightmare and resulted in the engine having to be pulled!

Just started reading,looks like one of the bolts wasn't playing ball!
Have decided,the engine is coming out.

sti v3 has underbucket shims if that helps, good decision on removing the engine will make life so much easier for you

Cheers banny
Been looking at a few YouTube vids and one had the shims loose/separate to to bucket and one had a fixed shim in the bucket,both were American vids tho so still not 100% sure if my underbucket shims are fixed or separate? Don't suppose it matters too much,just need to fix the problem and will know more when we pull the engine out.

before pulling the engine out check the clearances with it in.

Because of the lack of room, the bottom cap bolt wasn't possible to get enough force on to undo it and it just mashed the head. I should have just pulled the engine out to begin with.

Ok will do that before the engine comes out then.
Do you know the clearance measurements for exhaust and inlet please?
Or should I just be looking for consistency across all the valves?

I honestly don't remember off the top of my head. I have it written down at the workshop somewhere lol.

If i find it il pass it on.

You'll need a feeler gauge

Cheers :thumb:
The U.S. Vid was 0.015 for inlet I think and can't remember the exhaust(bigger gap tho) but they work in inches lol
I will make sure I have all the correct info to hand before I tackle the job.

Maybe of some help and worth dropping merlin24 a pm too for advice

Nice one for the heads up :)
Good thread that,and I know merlin24 knows his engines!

As Banny said, STi Ver3~4 have underbucket shims and the valve clearances are as per the link he put up.
You can reshim in situ but is a right mare to do, so always easier with engine out - just be careful you don't drop any of the shims into the bottom of the heads and into the sump when you remove the buckets !
I have good stock of shims if you need any.

Excellent,cheers Mick,I was about to drop you a pm about the clearance,I've taken note of your previous thread and will be in touch should I need any shims,hopefully it's nothing more serious.
Guessing it would be wise to check the other head while engines out,so will get some gaskets ordered.

The exhaust clearances do get smalller in use due to valve seat pitting/micro welding so always wise to check all valve clearances.

I will update my engine knocking thread when we've check all the valve clearance.
