Just out of interest, i asked the local Subaru dealer how much it would cost to set tappets on V3sti,reply-cant be done.

Might as well sell my car then i told them..."well we can do something but cant tell you how much!"

Version 3 might be HLA (hydraulic Lifter Assembly).

Cut and paste from Wiki:

http://en.wikipedia.org/wiki/Subaru_EJ_engine

EJ20G[edit]

EJ20G engines fall into 3 categories:

1. Rocker-style HLA EJ20G usage:[edit]

Legacy RS 89-93

Legacy RS-RA 89-93

Legacy GT 89-93

Power output ranges from 200 PS (147 kW; 197 bhp) @ 6000 rpm and 260 Nm for the GT to 220 PS (162 kW; 217 bhp) @ 6400 rpm and 270 Nm for the RS versions. Engines can be identified by coil on plug with 2 M6 bolts per coil and valve covers with 4CAM 16VALVE and horizontal lines above and below the plug holes. All these engines have the air-to-water intercooler setup (chargecooler) and oil squirters.

2. Bucket-style HLA EJ20G usage:[edit]

Impreza WRX 92~96.

Impreza WRX Wagon 92~96

Impreza WRX STI 93~96

EUDM Subaru Impreza Turbo 94~96

Power output ranges from 220 PS @ 6000 rpm and 260 Nm for the WRX Wagons to 275 PS @ 6500 rpm and 319 Nm for the WRX STI Version II. Engines can be identified by coil on plug with 1 M8 bolt per coil and valve covers with 4CAM 16VALVE and horizontal lines above the plug holes. Generally these engines all have the slanted intercooler. Some engines may not have HLA buckets but solid buckets with shims underneath. These engines also feature lighter valves, the intake valves are marked INKO and the exhaust valves are marked EXKO. The standard HLA valves are I252 and E283 respectively. All WRX Wagon engines and automatic sedan engines came with a TD04 with 90 deg elbow, all manual WRX sedans including STI versions had a TD05 with 9

3. Shim-over-bucket style EJ20G usage:[edit]

Impreza WRX AT 97~98

Impreza WRX AT Wagon 97~98

JDM Forester Turbo 97~98

EUDM Subaru Impreza Turbo 97~98

Power output is 250 PS @ 6000 rpm for the Japanese versions and 211 PS for the European model. Engines can be identified by smooth valve covers, plug leads and a wasted spark coil in the middle of the intake manifold. These engines were available with both manual and automatic transmission in Japan, but generally had manual transmission in Europe in the Impreza Turbo.

looks good but incomplete info, its missing the shim under. also we\'re talking about EJ20K

Next down on Wiki\'s list:

EJ20K[edit]

To identify an EJ20K:

Wasted spark coil pack on center of manifold

Inlet under manifold

Divorced idle air controller

Usage:

Impreza WRX & STi 9/96~9/98

Which would mean Dacca\'s Mechanic is wrong because the Sti uses Shim Under Buckets not HLA?

[boostedwrx]

Awesome rosssub tht b a help lols, went to a reputable machine shop today to see if they can make shims for me,, pozitive outcome ,,, yes they can 8) 8) ;D,

finally i can gt the motor back in, if i go down tht route, but ill wait to hear whatu come back with first,,, ive had absolutely no luck in finding a v4 sti, that someone will let me use their vin numba, any hu

cheers ppl

all you need is a rego. ring leighton at armstrong in chch hell sort you out .

whoever your talking to is being a fu$#en cock.

if you ask thorpy nicely he would most likely be happy for you to use his rego to get the part. well I used his cant remember if I asked or not lol

That^

Getting them machined separately would cost a small fortune compared to OEM. As said your "Mechanic" is being difficult. I\'ve had no luck finding Part Numbers at all? My replacement Heads arrived today so I can start measuring/ordering myself.

These are from the BH Workshop Manual I\'ve been using, Shim Over Bucket:

http://www.clubsub.org.nz/forum/index.php/topic,40353.0.html

Intake valve: S =(V + T) - 0.20

Exhaust valve: S =(V + T) - 0.25

S: Valve lifter thickness to be used

V: Measured valve clearance

T: Shim thickness required

I have done a bit of a search on checking and adjusting valve clearances on v4 shim under motors..

From what i have read the valves clearance should be checked at 105 thousand miles..

They can be checked with motor in car however it appears it is ten times easier to remove motor ..

It seems the motor should be removed if shims need changing..

Estimates of time to remove motor,adjust shims and replace motor is around 10 hours..

All this means that 99% of shim under motors never have their clearances checked..

That is until they burn the exhaust valves due to tight clearances ...

All info gained over interweb so could be dodgy..

However i shall check with my friendly mechanic when i next see him and report back...

[boostedwrx]

Awesom rex leggy ill gve him a go aswell, i take it thats his workplace ,, armstrongs,, and as for getting shims slightly ground its only $10 ea to get done, an $20 to get one made up aswell, so for ease of going up the road and an hour later thy done thts not bad lol,, ;D ;D ;D

still gna ring armstrong tho, because the more info i can get on these pita shims, the better, then everyone can share the knowledge, as im sure this topic has/does catch alot of ppl out, that also need the information also,

cheers ppl, enjoy the stinkin hot weather while it lasts

[boostedwrx]

Wow rosssub, uve outdone urself

thats awesome man, theres alot of info there and definetly gonna be usefull for someone 8)

cheers for the info bro, appreciate it

[boostedwrx]

Yayah, got shims from the machine shop today, $60 bucks for 7 now correct size shims, awesome job they did too,, cheers reid machining ;D ;D ;D

now its gonna be a long nyt but worth it ;D 8) ,

Nice, that\'s not bad. Wonder how much an OEM shim is?

[boostedwrx]

Was quoted by subaru taranaki, about $12a shim, and only if i cld supply part# or someone elses vin tag lols :-[

so yea not bad ae, have all shims in mota now and only and a gap.02 mm over on one exhaust, thank godcos it took me a week of measuring and swapping and measuring and swapping but hey was worth it, now who wants to help put moter back in place, lols

Might have to drag the wife to the shed for the night ;D

Is the Exhaust Shim 0.02 over spec, or 0.02 over the +/- 0.02 tolerance?

With the effort you\'ve put in already, motor still out and for the sake of $9. You may as well get it machined to perfection. Would be a good kick in the nuts to find an annoying tick from that Valve when it\'s warmed up and broken in?

[boostedwrx]

Sorry tolerance,,, its sitting @ .27mm exhaust,,,,, yea i should do but atm, i just wanna drive it lol, id seriously consider it,,if say it was .05 +or over but hey knowing my luck ill run a bottom end in two weeks time lols,, and have to pull it again anyways

[Rosssub]

That\'s within OEM tolerance so shouldn\'t cause any noise at all. I use the BEB motivation too. Higher Kms=She\'ll be right. ;D
