Well I have performed a cold engine compression test and numbered as cylinder 1 from drivers side I got 210-240-240-240. A nip of oil down cyl one saw my numbers bump up a smidge. I don't know what the allowable variation is but 30psi sounds significant.
Ideally you want them within about 10% so that's probably a bit too much of a drop, but the compression figures themselves are very healthy so I wouldn't be too upset.
Is the car blowing smoke under load? Get it looked at and find out if it's a valve or ring issue.
I'm just trying to locate some extra length feeler gauges to double check the valve clearances with regards to the compression variance before I look further. This week I'll try an oil change just in the hope of something changing. I'll see if I can chase a leak down tester.
Yeah Dougie prior to me wiring in the knock sensor it was blowing smoke under load. I haven't tried seeing what it's like since the sensor has been wired in.
I have just set all valve clearances and found all of them to be pretty generous. Most of the exhaust had pretty big gaps.
Rest to •155mm inlet and •178mm exhaust. Specs said •17 +\- •02 and •19 +/- •02
It was a little rattley.
I've yet to try it for smoke with the knock sensor wired up. I've also made an oil change to full synthetic. I'll see how it goes over the next few days.
Well I've come to the conclusion this thing is up for a rebuild. Damn it lol. Out it will come again. I can't stomach getting around in a smokey car.
Just deciding on a home build or off to the shop.
I've done a number of motorcycle engine rebuilds and 1 car engine rebuild. Not really sure I'm in the mood for a rebuild that could take months due to time.
Folks I've finally finally pulled this engine out for a rebuild. The machinist has informed me the current pistons are not up to spec. Well worn and a reborn to 1st oversize is on the cards.
I've called Honda for genuine pistons/rings. Price is $850
Looking at eBay stuff from the States. These two kits in particular?
