S30.World.com, order one and consider it done.

I have to ask why not just keep a set of spares that are still functional and enjoy the car? I applaud you for trying to fix the ECU if that is the end result you are looking for.

Go to the summit racing website and order a new champion replacement.

These units are primarily “pth” assembly. They have aged with time IMHO have passed there designed life span. There isn’t as far as my knowledge a test bench that will run it through post diagnostics. My suggestion would be to search this forum and find someone that doesn’t have any use for the spares they have accumulated over the years. Mine are gone to other folks in the same predicament.

You just previously posted a pic of what you think is a valve guide.

I’m not sure that’s a pic of a valve guide you posted.

I can’t understand why @Sean Dezart would shy away from any email. The S30 is his livelihood. Don’t care for making assumptions when we don’t have all the facts.

I contacted him Friday and he emailed me back Saturday. I told him somebody on the forum was having issues reaching him.

I know you don’t want to hear this as well but he’s been very responsive about information and tracking my orders.

@jonbill Where have you been friend?

Valve cover gaskets were never glued from the factory. Still available from Nissan.

Where are you located? Complete the profile. I didn’t see any information on my end.

AHH, You didn’t go for the 3.1? 😂

What’s the matter with Cliff??😂

@solly I don’t believe you answered my question about the check valve. Trying to offer known problems that cause what you are describing

Is that a reflection on the sugar scoop or are those brush marks?

WD 40 will swell the rubber IMHO.

@mayolives do yourself a huge favor and research the disc I’m talking about located on the the end of the pushrod inside the booster. There are rebuilders for that booster.

That’s good advice but you didn’t warn him about the disc dropping to the bottom of the booster.

@Mike Can’t you block this somehow?

@jfa.series1 I need to be schooled AsWell!!

Did you remove the check valve on the booster vacuum line at any time? If you installed it backwards that will cause the problem you are describing.

It’s truly a journey. Been there and it takes awhile

You are correct… That pan is thick aluminum and the baffles inside are just amazing. Not sure I will make it to the track. It’s a stage 4 build from Datsun Spirit. Eiji did an amazing job.

@Mike I guess it’s going to be just like the ocean, It’s not going to stop.
