Well oil changed and filter put on..no bits in old oil..thought that's good sign until engine warmed up and tick tick tick so its down in the most reliable place of the three arches with dean and Dan stripping the block to find out problem,dean said its probably big end bearing going and that's how it's loosing pressure, so gonna send block to lateral performance to get it fully closed then back to more than capable hands of the guys to fit back. So hopefully she be bullet proof!!

 

Not good news that fella, I'm sure the guys down there will get you sorted and the cars in safe hands

 

Blinking flip, sorry to hear this Bryan - you'll be in good hands with Dean and Dan at Three Arches.

I'm going through the same thing myself at the moment, who built the engine as hasn't it already had a forged build?

 

Its a forged build and only done 20 thousand miles since build and most of that was running under 300 bhp and under 1 bar of boost.. More disappointing Roger Clarke Motorsport done the build

 

It's got to be worth contacting them and seeing what can be done, nothing ventured, nothing gained.

 

Not what you need

No matter who built it if the mapping is not right your heading for trouble.

Something was not right for this to happen to a forged build, it should of been ultra reliable .

 

Already contacted Olly Clarke,but he wants to know what has gone wrong but no immediate help even though engine of its build with omega pistons shouldn't even be working hard at just under 400 bhp\torque. He did mention if fuel was run too lean it could chew a piston up? Is that down to mapper to get fuel to run correct?? Just looking for possible answers?

 

Map issues can cause lean running for sure, sorry to hear of your troubles here.
If you don't mind me saying if I was in your shoes I would not plough head first into this for a minute I would be trying to find out why this happened initially, I would be tempted to ask Dean to put you a report together with photographic and saved parts evidence to what has happened this may then lead you to discuss further with other involved parties as to a why if you can.

 

Dean and Dan will fix it, but even if I got photos or evidence of the parties not doing a job right, I probably won't get anywhere as the buck will surely be passed about. How could you tell if fuel was running lean etc?? What would I do then? It sounds like a round about for a long time. Do I have rights if its buggered up my engine?? Cheers lads for concerns

 

If it's down to the bottom end as Dean thinks then that wouldn't be down to the map, I'd personally be looking towards faulty manufactured part or even if it was run low on oil at some point before your ownership Bry. Another thought would be low oil level along with hard cornering?? The latter happened to a Celica GT4 I owned, done the bottom end and cost me over £1800 to put right. Keep us posted fella.

 

Deano will put it right,probably go to lateral performance to get block fully closed and I'm never gonna use nobody else in future to p**s about with my car. She soon be back kid waking up the neighbours

 

Sorry to hear this bry!!! Dean and Dan will see get it sorted for you mate.

 

Saw the poorly Scoob earlier Bry. It was sad to see but it will be sorted soon.

 

Yep she soon be back was you down there getting your car done or grabbing bits?Once engine sorted then front paint job for stone chips and refurb wheels and she be ready for the shows..Cant wait for japfest!!

 

Be all good now kid in few weeks I feel quite relieved in a strange way that ive found a weakness now not later on in car life,could romp the power up a bit more now! No I wont I be good boy she is quick enough

 

I try and keep a foot on the ground with the guys. Dean's got a little runabout I may get as a 1st car for my other halfs son.
It's on my doorstep so I go and annoy them regularly, I think I may owe them some biscuits.

 

Sorry to hear this Bry.
The trials & tribulations of:
a: Subaru
b: Tuning

When she's back and shes been driven steady for 500 miles or so speak with the right guys for the map. You know who they are.

 

Where do you plan on having it mapped bry once all the work ect has been done? I went up to powerstation last week for mine and to be honest they were great, very nice guys and knew what they were up to. I wouldn't hesitate on going back there for any map work they also sorted me out on a price that was very nice of them

 

Probably powerstation fella

 

Just an update of the scooby..big end bearing failure due to low oil pressure. Deano has stripped engine to find no4 bearing not looking good! Oil level was full so said oil pump failure it had an rcm uprated one as well which i dont understand why its gone caapoot! Not sure of direction to go now,do i just get it all fixed or go fully closed deck? Another option is to buy a donor engine with all the bits already done?? Advice! Lol

 

Nothing is reliable kev and no matter how much money and best parts you put in to an engine or who builds it for that matter , running good power or high bhp I have seen it many times over the years and been told a few times the more you squeeze out of an engine its not going to last, forged or not it's more of a how lucky you are going to be as it's always the bearing on the crank that give in the end

It's always sad to read about these problems and I'm gutted for Bry

I learned the hard way that's why mine is staying standard and just keep it serviced and looked after and just appreciate it for what it is

hope you get it back up and running soon bry , gutted for you and been there myself a few years ago

 

Ah cheers kid, soon be back up running just not sure what path to take..fix,rebuild or donor engine with bits already on for power?

 

if there was an issue with the oil pump it would likely only be caused via loose bolts on the rear housing or the relief valve jammed - mapping can/does cause bottom end issues far more than people believe as it can cause shock loads on the bearings and also higher than normal temps...........
the fact its run for 20K+ would normally rule out a simply "build fault", etc......

if you want a CDB try our conversions which we have done for numerous years as well as supplied to various other tuners........

I know where your coming from bry so many choices these days and picking the right path to go down is hard and sometimes stressful

good luck and hope the path you take will do you well

 

That's interesting to read, I never thought mapping could potentially cause bottom end damage.

 

specifically its poor mapping causing DET, lean running, etc.

repeatedly bouncing off the rev limiter also causes shock loadings

 

That is interesting
