EJ20 N/A missing on all 4 cylinders
EJ20 N/A missing on all 4 cylinders
Well I was doing some nuts the other night offroad to celebrate my 200,000km tick over on the Forester then all of a sudden it was running shitter than usual.
There is a miss on all 4 cylinders, I have checked with a timing light. Changed all spark plugs, leads and put a new coil pack on. New knock sensor and reset the ECU.
It's still running extremely shit and I would atleast like it to run on all 4 properly...
I thought about the crank angle sensor, but then the car wouldn't crank only turn over so I'm not sure that it's that. What about the timing belt, could that of jumped a tooth causing the car to run like shit?
Any ideas?
Thanks
Taz
Oh: got my EJ25 heads back from the engine shop The rest of the block goes in on Monday for a light hone and clean up...
Heads are fully recon'ed. New valves, valve springs, VSS, pressure tested, cleaned up and all the rest... I thought about a bigger cam but I'll leave it for now

What is the fuel like? Contaminated fuel? And is the pump working well?
Is the timing belt in correct position/lined up?
Wont be related - MAP/MAF sensor?

I have fueled up 4 tanks since this has happened and that has changed nothing. It does it at all revs, including idle.
I haven't checked the fuel pressure...
I haven't checked the timing belt, but I thought that it could be possible that it has stretched and jumped a tooth... It is way over due but since I'm putting a new engine in in a few weeks I wasn't going to bother changing it..

If the timing belt was stretched - it wouldn't line up... hard thing but you will have to count how many teeths (because the markers would have worn off) in between if it didn't line up - if you were there you might as well replace it to new one.taza wrote:I have fueled up 4 tanks since this has happened and that has changed nothing.

How about any leakage in air manifold section from airbox to inlet manifold? (engine wouldn't idle if there was a leak)
Compression issue?

Wow.. heads look good Taz
I would look for a hose off somewhere and there is a possibility the belt may have skid/jumped a tooth but you'll only find out by removing the covers.
Let get this right, you were out flogging the crap out of your car and you're wondering why the gearbox is giving you trouble

How did the timing light tell you there was a miss? Irregular flashes I'd guess at a set rev - if they were regular all is good there.taza wrote:There is a miss on all 4 cylinders, I have checked with a timing light.
If it has in fact jumped a tooth or two on the belt there must be something wrong with the cam belt system and this could get much worse very soon - I had a bearing collapse on an idler pulley after being in a puddle of water.
If you have skipped a tooth or two it must have either been done on the crank gear so that both cams are the same out or both cams must be out differently. Either way it will never be smooth under any conditions - it will always be lumpy - VERY noticeably lumpy...
If you're ever going to go for a cam now is the best time to do it with the heads on the bench - once in the car it'll be a pot load harder to do (but still possible).taza wrote:I thought about a bigger cam but I'll leave it for now

Pretty common on earlier rally cars to jump/skip a tooth or 2 on the belt. This was mainly due to high revs and on/off loads very quickly. The later EJ engines, Subaru fitted a retainer over the top of the crankshaft pulley.
I'm not saying this is definitely what's happened but I wouldn't rule it out. You might also want to check that your coil isn't 'tracking' to the manifold. This happens quite a few times on engines that are around dust a lot.

Nope.. factory fitted by Subaru. Will post pic latersteptoe wrote:retainer ? Is that the extra gadget in the box that Gates? are claiming to include to better safeguard your new belt install ?

That should solve your gearbox and engine problem.

Thanks, I'm happy with them. The rest of the block is going in for a light hone and clean up on Monday(tomorrow).RSR 555 wrote:Wow.. heads look good Taz
All the hoses seem fine.I would look for a hose off somewhere and there is a possibility the belt may have skid/jumped a tooth but you'll only find out by removing the covers.
Yes I was flogging it but I am kind on the gearbox and gear changes. Been there and done that, learnt my lesson! Plus once your in the right gear all you do is hit the gas pedal to go sideways :PLet get this right, you were out flogging the crap out of your car and you're wondering why the gearbox is giving you trouble
Irregular flashes every 5-6 flashes it would miss one. All 4 clylinders did this at different times. The engine runs really lumpyEl_Freddo wrote:How did the timing light tell you there was a miss? Irregular flashes I'd guess at a set rev - if they were regular all is good there.
Possibly, this was a used engine with 200,000km on it when I got it. I know nothing about the history of it.If it has in fact jumped a tooth or two on the belt there must be something wrong with the cam belt system and this could get much worse very soon - I had a bearing collapse on an idler pulley after being in a puddle of water.
This is what it is like.If you have skipped a tooth or two it must have either been done on the crank gear so that both cams are the same out or both cams must be out differently. Either way it will never be smooth under any conditions - it will always be lumpy - VERY noticeably lumpy...
Problem is $$$ otherwise my EJ25 would of been in months ago.If you're ever going to go for a cam now is the best time to do it with the heads on the bench - once in the car it'll be a pot load harder to do (but still possible).

My car is around heaps of dust most of the time, could possibly explain the clutch/gearbox issues tooYou might also want to check that your coil isn't 'tracking' to the manifold. This happens quite a few times on engines that are around dust a lot.
The coil isn't tracking, I checked the other night..
