It's got less kms than your motor, so should by all accounts be in better condition. If you are doing that, put a little amount of copper seal around the plug Seals.

I think there is a rubber line outer seal to replace too, that sits in the cover? Scotty? Should only be a couple of bucks.

Yeh, the rocker gasket is around $25.

I don't like putting sealant around them, as a thin smear might fall off and partially block the oil pump or pickup (as there is nothing to hold the sealant in place). I try to minimise the use of silicone inside the engine for this reason.

Should tell nissan that... Whole thing is held together with sealant! :P

I never had an issue with it when I was changing sumps over. No sealant disappeared. As long as the instructions are followed, the stuff works well.

If you use tons of it, and clamp it down hard immediately, then your right, you're in for a bad time.

I will say it again for the deaf among us... There is nothing to hold the sealant in place, and nothing to clamp it.

As the tube is covered in oil the sealant won't stick, and there isn't another mating surface to hold it in place, hence why it will break off and float about the engine. It's a slightly different application to sealing the sump as there is a 20mm lip holding the silicone in place, plus you would be able to scrape it clean first and brake clean it.

I see what Scotty means.

The sealant wouldn't help. It's just a thin metal edge.

Yes, but Nissan still used a little sealant on the cover gasket, at least mine had some when I removed it. Someone should tell those engineers the theory & see what they think....

On sealing around the spark plug tube, totally agree - it's pointless. Better to syringe it out every so often than risk it.

It would have just been nice for them to just round off the spark plug tubes at the end to just a little flat surface, so it would seal better. But alas, I suppose the accountants got in their ear. Probably one of those will it last 3 years/100k kms things. Even the old honda I had (honda boi!) had a better mating surface.

How do you deal with no vtec? It must be so boring driving your s13.

Hahahahahah

My little shitbox didn't even have vtec! It was a uni student car.

I think it was before the whole vtec fan boi thing. The vtec models were pretty expensive in 2002, so kids couldn't afford them.

Nup, it was actually on the quarter mile it blew up.

The motor was suffering massive amount of Det, and was shedding the electrodes from spark plugs. One may have come off and rattled around, but it looks as if the det blew out the side of the piston rings too. You'll see more once you remove the piston and rod.

    • Just to be clear, there were no lights or codes when the hiccups were occurring. Also nothing noticeable in the cars' braking. It brakes fine and the dash is clear. I only made the connection when it did throw a code and suddenly, despite the lights, it felt great again. 
    • Yeah they are sliders and this was in my head before I worked out it was the speed sensor.
    • Ok so we have a smoking gun.  A few weeks ago I had to replace a speed sensor that I'd fit incorrectly. I replaced the sensor and everything was fine with no lights or codes thrown any longer.  When I was doing some more bedding in yesterday I got ABS and traction control lights again and, considering when this happens those things are disabled, the pedal went back to normal with smooth braking and no hiccups.  The codes thrown are for the same speed sensor that I replaced. When I looked at the sensor I took out it looks like the tip of the sensor is damaged. So whatever happened to it, perhaps it has damaged the magnetic ring on the bearing (that I only replaced the other week). I'll get my boroscope in the hole where the sensor goes and see if there is any damage in there. Hopefully just the tip of the sensor is in there and the bearing is fine. 🤞🏻  It's worth noting also that the pedal hiccup happens more often and for longer periods now and totally goes away when the codes are thrown again which happens usually after 5 or so minutes of driving. Love all your help here as usual guys, thanks!
