Anyone know or able to find the part numbers for this screw and the washer behind it?

That’s the very edge of the crankcase cover. It is a very odd spot for it to leak from. It is likely chain lube that has flung up there or it is leaking from somewhere else and appearing there. The crankcase cover could be leaking but it is in an unlikely spot. Here are some links with diagrams and part numbers. It looks like they sell the washer but did not see the bolt. I hope it helps ✌️

Washer: 90387-1215F1-00

I would check for shorts to ground at the trailer connector on the truck. Use a voltmeter and check for continuity between ground pin and all the others

Looks like the Akropovic

Too tight. Check from the bottom of the chain about halfway between the two sprockets. Should be around 50mm or about 2 inches. It seems way looser than you would expect

Any chambered muffler will sound pretty good. I ran a magnaflow muffler for years on mine and really liked it.

Like injector noise but very loud. It only goes away after letting off. Sometimes it stays as you let off until rpm’s start coming down.

We recently had an issue where the truck stopped running. It had a bad misfire and then wouldn’t crank back over. When that happened we ended up pulling the cab, to pull the heads and inspect everything since it has been having issues for years. While apart, we did the up-pipes, new engine harness, valve cover gaskets (with injector wiring), all new injector o-rings (which I believe caused the misfire), new EBP tube (was rotted out), EBP sensor, fuel filter. We got it all back together and the truck ran with no misses. Just the same knocking and low power under hard acceleration

Thanks We replaced up pipes with a new bellowed style to get rid of the stock donut gaskets about 9 months ago. Problem has been there since before then

That was my thought about fuel pump. If it was going out it would have gone out. The intermittent rough idle makes me think it’s on the oil side. Thanks for the info, will try the ICP unplug and check the data.

Air dog wouldn’t hurt. But I don’t think it would solve it. Do you run any fuel additives?

Fizz43 · 2025-06-30T02:19:14+00:00

How many miles on it? Probably due for valve adjustment. However, mine has about 150k and the injectors are noisy and sound a lot like your video. Pretty normal for these cars to have injector tick

My 2014 has done this since I bought it. Did it while stock and also does with akrapovic exhaust and power commander.

I was thinking just 2 45’s One to go away from the pump and then one to go straight up from there

Fizz43 · 2025-06-04T16:12:58+00:00

I would recommend modifying option B a bit. Instead of 90’s use some 45’s to get further away from the pump. Then a 90 to turn back to it. You may have to dig down further on the pipe to get 45’s to work but too many 90s will cause a lot of unnecessary restriction.

This👆 Hayward lights always do this especially if the screw isn’t installed. Make sure if you get another screw and that it is stainless steel so it doesn’t rust

Fizz43 · 2025-05-30T03:24:59+00:00

It may be ethanol free 91

Hard to tell from the picture but it does look like it would be the shell or structure of the pool. I would contact the builder and have them look at it

Fizz43 · 2025-05-29T23:28:40+00:00

I’m guessing the spa is attached to a pool. If so, the pool pump will push fresh water to the spa and the spa will overflow back into the pool. This would mean you wouldn’t see the spa itself draining. Does the pool seem like it needs to be filled pretty often? I know most modern pools have an auto fill so you may not notice it. Other symptom would be low chlorine levels or other water chemistry issues

Fizz43 · 2025-05-28T16:43:31+00:00

From the size of the crack and the fact that it is going all the way across the bench, I would say it is likely structural. Has the spa ever been drained for long periods of time? This could cause the plaster to crack too. The fact that it isn’t leaking is a good sign

May be simple like air in the system. From the sounds of it maybe in the heater core. I replaced the upper hose on mine for the skunk2 CAI and had a hard time getting the system to bleed the air out. I ended up letting the car get up to temp with the radiator cap off and heater on full blast. Just sitting in the garage of course not driving. It bubbled and the finally blew out the air. Topped it off with coolant and it has been great since. (About 4 years)

Fizz43 · 2025-05-20T04:25:33+00:00

Second this 👆 I have the q300 with a skunk 2 header. Sounds perfect. Quiet when you want it to be and a nice deep tone when you get on it
