Few niggly jobs cleaned up one was the oil filler cap was leaking so went to halfords and bought a new cap just so i could use the new rubber
Have also had a leaking sump since the new block and head went in so drained the oil and flushed it through for 10 minutes with some oil from work, then whipped the sump, windage plate and pick up pipe off and cleaned it all up, while it was off i thought i'd double check how close the pickup pipe was to the sump base, put it on my mock up engine and turns out it was way off (i didn't make it) so a quick bit of cutting and re welding and it was as it should be
While it was out a blew through with the air line my oil pressure gauge feed pipe and was checking all oil related components as for some reason i have only been getting 40psi of oil pressure regardless of load or cold start, noticed this the last time i started it up so knew something was up everything seemed fine until i tried to get relief float out, it was stuck solid into the shut position I knew this was wrong as i've had the spare mock up one to bits and that glided out, finally got it out by using my scribe and hanging off it until it came out, you can clearly see the score marks on it which at the minute i have no idea why it has them or why it was stuck shut :dunno: Anyone got any ideas?????
So luckily for me i may have just found the cause before my pump failed and killed my engine (pumps done about 1500 miles tops and is a genuine GM Z20LET pump) I may be the first with this problem but i recommend everyone checks theres
Was getting late so called it a day but will clean the bore up with oiled up wet and dry and also give the float part a good smoothing and check for movement before reinstalling. Have used a small amout of sealent on the 8V gasket and sump so am letting that fully cure overnight before i top up with new oil tomorrow. Other small jobs have been to move the wideband sensor to its new location, still need to buy a new one though
Glad to see your sorting bits out Out of interest who did the pump pick up pipe?? As for relief valve...... wow has it scored inside too??
Where you only ever getting 40psi of pressure then?

I dare any of you to tell me you wouldn't let this upstanding young citizen slob on your knob like corn on the cob.
Started putting the corsa back together today, re wrapped the top part of the down pipe as it has worn a hole through where the boost pipe crosses it so triple wrapped it in that place
Also cleaned up the relief valve with oiled up wet and dry to remove any score marks before re fitting, now glides up and down nicely. I took apart an old c20let/XE pump and checked to see if the relief valve was the same and it turns out they are so I will order a nylon one from SBD tomorrow just for piece of mind
Topped it up with the new oil and let it run up the oil pressure is back up to 65psi at cold idle and rises with load so chuffed about that i also have no leaks at all from the bottom end so that's a massive bonus
On a down side though my V clamp joints still blow which is annoying as I've tried all sorts to prevent this with no joy :cry:
Also on it's last drive when I was giving it a bit of stick it started to miss fire so assumed I lost a plug again as it went into Subaru sounding mode again so nipped halfords and bought some more RST plugs
Replaced them and the battery as that was dead and still the same :cry:
Went to Robs to use his compression tester they all came back fine, have heathy spark and fuel so must have an air leak as my revs now sit at 1200-2500 so will whip the boost pipes off to check for split silicones or joins but will order a new inlet gasket as well as tbh that's the more likely cause I'd of thought
New parts all ordered gonna get them all fitted up this week at work and hopefully car will be back up and running correctly

looking gd m8.
same happend with my relief valve ony mine was the sbd valve, Now i just have my std metal valves polished to give a nice smooth surface never had any problems (YET) lol.
N/A is the way......
New Wideband sensor fitted and gauge now working as it should so happy days
Removed the fuel rail as I had got a random leak all of sudden and removed the inlet to find my leak, turns out the gasket was soaked in fuel and gone soft in the corner and under boost it blew a bit out :cry: Also two of the injector O rings had chewed themselfs up so replaced them as well
And the damage
Have re sealed the end of the fuel rail with fuel resistant sealer so had to leave that to dry before I start her up again
Fans turned up from Fenny
Gave them a good clean up and altered the wiring loom to suit and fitted up
Had to cut the headlight metal frames out as because of how my turbo sits it is further forward all cut out and fits perfect
All back together but can't drive the bloody thing as my injector O rings are pissing fuel :cry:
New ones are already on order so may look at modding the rail as there is no taper on it
nice one mr dewis.
Roll on LET power....
good stuff mr dewi..keeping the beast all sweet and respected

O rings have turned up so will fit tomorrow hopefully gonna see if i can put a taper on the fuel rail as it just seems to be chewing them up every time i re fit injectors as the holes are so tight :cry:
Also ordered a pair of 350lb 7" springs as the 9" are too long for my liking and i think even the 8" would leave me no adjustment for fine tuning the ride height so my own fault really
looking good adam, is that the same fuel rail i'm using???
