Pics.

And no sign of that rusty manifold!

Oil leak or coolant leak? Either one sucks.

[95CelicaST]

Oil leak. We’re currently digging into it now. So far it doesn’t appear to be cam seals. We’re removing the crank pulley now.

[Bitter]

The oil pump perimeter seal and the oil pump shaft seal are prime leakers, that perimeter seal can be tricky to lay flat in the groove all the way around. The shaft seal usually only leaks when the shaft is deeply scored, doubt thats your issue.

[95CelicaST]

Found it. It was a dumb bolt that goes into the oil pump that was missing. We grabbed the old pump and removed the bolt. Cleaned it up, and no more leaks.

We’ll put it back together tomorrow.

It’s off to the tuner tomorrow AM.

Loaded on a flatbed and brought it to my tuner this afternoon.

my heart knows its still there.....

The Rusty Manifold, good name for a gay bar.

I asked my tuner to start with a preliminary base tune that I can break the engine in with, and then I’ll schedule it back in for max power after.

Well I popped in today to check in, and they had it up on the dyno doing some partial throttle fuel changes. Turns out the coil wire is arcing to the catch can, causing a miss. New wires will be here tomorrow to replace the cheap ones I got from PrimeDriven.

I’m hoping it’s ready to go tomorrow. I have an alignment appointment on Saturday, and then a car show on Sunday.

So much progress, and it's almost all over.

[95CelicaST]

Well getting it ready for a car show this last weekend I found that the coolant overflow port on the coolant neck broke off and leaked a little bit of coolant. Looks like it wasn’t even welded in, but rather just epoxied.

So a mild bummer, but thankfully Racer X sells their own version, so I got that on order. I also pulled the trigger on a Racer X center feed intake manifold and 75mm Mustang TB. With any luck the coolant neck will be here this weekend, and the intake manifold in a few weeks. We’ll install it when it’s time to go back to the tuner to dial in the power post-break in.

At the same time we will convert to Coil on plug. I have the hall sensors and cam and crank trigger wheels to get that done, as well as a set of 1ZZ coils, although from an aesthetic perspective they don’t please me. I also have a set of 1NZ coils, which I understand are just as strong as 1ZZ, but cheaper, and the connector is flat, rather than at an upward angle.

My Innovate LC2 arrived today, so that’ll get wired into the ECU.

Can you get something to cover the coils? I have a nice semi matte black steel plate that bolts down to my valve cover on the Celica and covers the coils, looks real good.

The valve cover doesn’t have any provisions for something to bolt on top to cover them. There is someone who makes a cover for the Gen4 3S, but the valve covers are way too different. I couldn’t use it if I wanted to. It is just that the plate to bolt the coils down to has them all at different angles, which is fine from a functional perspective, but I can’t imagine it being too difficult to just get them all lined up the same way. I have some buddies that may be able to 3D print something else. We’ll see.

[95CelicaST]

Not many updates for now. Racer X sent the coolant neck and I installed it, and cleaned the dried Toyota Red from the top of the transmission. I drove the car once, and then the alternator started to undercharge the battery. I didn’t have time to look into it until yesterday, where I found the nut had completely backed off the power wire, so I got that tightened back up and went for a drive.



Filled the tank and calculated initial fuel economy. 224.6 miles and 9.456 gallons to fill up = 23.75mpg, or 10.09 km/l.

Still waiting on my intake manifold to ship. Hopefully this next week.

I was looking at those, too, for my 2nd gen and upon laying my eyes on the photos, I said to myself, "Them hoes look uggo...."

The intake mani has shipped! I should hopefully have it by Saturday.
