![]() ![]() In 2006 to mark the 30th anniversary of the Accord, Honda created the J30A5, which boosted output to 244 hp (SAE Net 08/04) and 211 lb The IMA hybrid version was on the list for 2005. This version was on the Ward's 10 Best Engines list for 20. It weighs nearly 20 lb (9.1 kg) less and is an inch shorter than J30A1. m) using a three-way VTEC system, higher (10:1) compression ratio, and a novel exhaust manifold cast as one piece with the cylinder head.The J30A4 pushed output to 240 hp (180 kW) and 212 lb Output for the light weight 250 lb (110 kg) J30A1 was 200 hp (150 kW) 5500 rpm and 195 lb Bore is 86 mm (3.4 in) and stroke is 86 mm (3.4 in). I’ll post a link in a second.The J30A displaces 2,997 cc (2.997 L 182.9 cu in) and is a SOHC VTEC design. If you think it’ll help, check them out on my YouTube and let me know. I have some diagnostic videos I recorded using the TORQUE track recorder while trying to diagnose this and other recent car issues. Unfortunately my dad tossed his gauge, so I’ll have to see if a friend has one. If you still get the same readings, we’re into some very interesting territory. I’d try to borrow another gauge and do the compression check again. Maybe the gauge’s mechanism isn’t going wonky until it goes above a certain point in its range, and you didn’t reach that point when you tested the gauge. It makes sense that combustion chamber deposits will raise an engine’s compression ratio, but I think an increase of over 60% is a bit much to believe, especially since the readings are so consistent between all cylinders. Your compression ratio is 10:1, so you should be getting readings not much more than 147 PSI. At that ratio and heat load, you’d think your engine would be detonating itself to pieces when running. I did some quick arithmetic, and in order for your engine to make 230 PSI during this test, it would have a static compression ratio approaching 16:1. But perhaps the power loss issue is causing high compression? Could the stop leak and 10w30 do this? I’m having major power loss problems too as I previously mentioned, and I highly doubt it’s due to the oil and stop leak. I only put 1 maybe 2 quarts of 10w30 in tops. What are the chances of that happening if it’s due to carbon deposits?Īnother thought: I used Lucas stop leak twice now, and the second to last time I needed to refill a little burnt up oil, I only had 10w30 (it runs on 5w20). That’s the explanation I always see online, but all six cylinders? And they’re all within like 15psi of each other. ![]() A bore scope would be handy right about now to peek in through the spark plug port. The air gets more compressed (because the combustion chamber is essentially smaller) and the pressure reads high. High compression in a cylinder usually means there is liquid oil and/or high carbon deposit in the combustion chamber displacing room for air. ![]()
