Jesse888 Forged/stroker turbo ek9


Not yet, stuck my finger inside and the oil was silky smooth. Will get the chisel out tomorrow and have a good look.
Honestly the metal in the oil isn't THAT bad. Obviously still a cause for concern but isn't as serious as it may sound/look

How would I check it out the car? Take it I'd need some form of rig that the crank can turn on?

Yeah two v blocks would do. But they would need to be high enough so the crank can rotate. Then use the DTI on the main joirnals. That be the easiest way. There are other ways but need more specialist equipment.
 
Did some research on it yesterday. Read that you can leave it in the block but only have it supported by mains 1 and 5.
I'll be taking the pump off later today so should find something there.

Got the vtec solnoid off, alittle bit of what looks like paint in the mesh but nothing I would call blocked. No noticable metal build up either. Will take the cam cover off and have a poke about later.
Haven't pulled filter apart yet but that's to do.
Oil pump is the reason for pressure loss, now to find why.
The gears in the pump have pitting and scoring, Pitts in the deeper grooves of the pump and scoring on the "teeth".
I think if it was sucking up crap it would just be pitting but this is just guess work from me tbh.
What did your pump look like when it was crap sucked up? Any scoring @b16 mini ?
Here's some pics, I'll clean the gear up abit and try and find evidence of the crank being bent from any damage to pump but I'll wait for DTI to confirm.



Pretty sure the scoring around the outside of the pump is from the swarf coming off the gears, could be wrong of course.
 
Just a thought, I had my cam cover welded up just before I went on track, I washed it best I could but perhaps I missed some swarf and that's ended up in the pump? Was a fair bit of it behind the baffle in the cover but I think it would be unlucky(read unlikely) for it to end up in the sump and then the pump? Wouldn't end up on the sump plug because it's ally though so possiblity?
 
looks just like mine, maybe not quite so deep pits and scores,

Scores round the outside is just crap being drawn in to the side clearance gap,

This does just look like classic pump failure due to crap pick up,
 
So what's your opinion on this?
What did you change when yours went?
 
I think you really need to pull some bearing caps, mine damaged the mains more than big ends, yours may not of gone so far hopefully.

When mine went I put together a spare bottom end that I had laying around (was just a b16a)
 
That's the next job after pulling the filter apart, check some bearings.
Ah so you used a different crank aswell, chances of a crank being bent though? We'll see...
 
There will be tell tale signs on the mains if it's bent, just have to wait and see I guess
 
Good point! What am I looking for uneven wear across the width of the bearing? Or like a low spot in the bearing material? Might have got lucky and it's just **** in the pump. Fingers crossed
 
I know @Rich777 had similar issue of debris suck up as well, could be interesting to see how his looked as well
 
Your damage from 1 piece of debris you think? Suppose once the pumps gears are pitted the problem just builds on itself.

Think Rich mentioned it was due to some metal fall out that may off been in the sump after he welded an oil return. Sacrificed his oil pump.

Anything that looks unusual really, obviously you can only check the bottoms of the mains for now but you should be able to remove both sides of the big ends although it's a bit fiddly, get some pictures if in doubt
 
Yeah I'll picture them for you guys, I'm a novice at best at this sort of thing but willing to learn if someone could point out why a certain wear pattern shows the cranks bent etc.
Getting more help here than on my other thread atleast. Not on any other forums so this place is my only hope lol

Hard to say, like you say it just builds on its self once it starts
 
How long did you go before changing the 1st batch of oil?
Could be that the oil has picked up debris from the oil galleries and its made its way to the pump. That's the reason I change it as soon as the engine is a mile or 2 old. Pretty much let the oil pick up debris (if any) and then flush it out.

Really hope the bottom end is ok. the crank shouldn't be bent, but I would check all the bearings just to be sure.
 
123 miles iirc. Way too long when you think about it.
I had a lot of idle time aswell so if you counted hours running it's even longer.
I'm hoping your right, I'll happily replace the bearings,pump etc but finding another crank is a pain in the arse. I'm not that unlucky to have a bent crank I don't think. But whatever happens happens i'l take it when it comes.
 
So afew updates.
Got a new pump ordered, found that the sump had been dented and that had pushed against the oil pickup pipe.
I found more crud in the pick up pipe so I'm just going to replace that with a new one, not worth the risk of sucking something else up from it.
Next problem after the engine was the noise limits, means I have to run the wastegate back into the down pipe, so no more screamer:( extreme sad!
Does mean I got to do something alittle creative which was nice.

I've since welded it up(not very well) luckily my buddy welds for a living so he'll redo it for me.
Also got this silencer for the centre section, will replace a "cherry bomb" style silencer so hopefully all this will see me wayyy under any limit we are likely to see in the uk.
