Alright so I’ve been trying to get my car to start and I’ve done a lot, what does it sound like my car is missing now? I’ll add a video, I’m just lost

If your engine has never been touched before go with oem standard bore.
That’s what I was thinking but I thought the standard bore was 85mm and the only ones I can find that are 85mm are graphite ones and I’d rather not put a graphite head gasket in my car, so I was looking at cometic ones but I can only find it in 85.5mm at .056 so I’m not so sure what to do, also that was on stm tuned but I haven’t looked on eBay yet but i will if I have to I just wanted some input.

You need to do a leak down test to determine the cause of low compression first. Or at least a wet compression test to verify it’s not rings.
I did the wet test on it last week and the compression raised by about 2psi on the two low cylinders, I didn’t do #1 and #2 bc they were reading at 120 for #2 and 150 for #1 so then that made my assumption it’s blown in between cylinders 3 and 4 if I had to guess.

Before you buy and avoid the same mistake i did, if you going to open the engine do it first and inspect all engine before buy any part

The last time i buy oem bore size piston, oem head gasket and when i start working on it the block have deep scratches and we need to bore it and now i have a spare of new stock size piston useless for me

Well good news is I had already planned on pulling the head off first before I ordered it just to make sure there wasn’t anything else down inside, also I’ve done main bearing and piston rod bearing and pushed the pistons up to the top while looking inside the cylinder walls, I couldn’t see any major scratches or anything like that but obviously it won’t be a good a look as when the head is off, but I’ll see what’s underneath.

I might not have mentioned it, but thank you for clearing up the sizing and is it also .056?
According to cometic via stm’s website the 3 layer .056” is oem thickness. I realize I probably got that info from the same place you did. I don’t have an oem one on hand to measure. I do have a felpro composite if you would like any specs from that.

Are you planning on having the head resurfaced? It’s recommended for MLS gaskets.

I wasn’t going to take to a machine shop to get it resurfaced I was just going to smooth it out myself, so then I assumed I’d just use the stock specs for a head gasket

Not doubting your skills, just thinking that since you had/think you had a failure of the HG already, that you really need a perfect block and head to use an mls gasket. You may want to consider composite if you’re not going to use a machine shop. Just a suggestion.

Check the flatness on both surfaces with a straightedge and feeler gauge. I don’t have the specs. Hopefully someone can post that. I wouldn’t try to resurface the head at home tbh.

According to the various FSM the specs are:
Flatness of gasket surface Less than 0.05mm (.0020in ) Limit 0.2mm (.008in)

You would have to check with the gasket people for the surface RA (Finish) for their gaskets but with MLS gaskets they pretty much look like they are satin polished finish when they are the right RA.


Last but not least, the head and block should not be flattened on a belt sander but machined with a stone or flycutter on a mill and only if they are not flat. Once removed, material can't be put back. This isn't something most home shops can do right.

I can’t afford to have it machined at a shop but I have a buddy that has built his car and gone through the motor many times and has resurfaced before so I’m going to have him do it.

If you’re going that route, I highly recommend sticking with oem composite hg. You’ll have a higher likelihood not to seal properly with mls hg. Good find. A leak down would have shown bubbles in the coolant system.

Put a L on my block earlier and felt under each section with my feeler gauge and I couldn’t put the feeler garage underneath any part, I was measuring using .004” on my gauge. I’ll check the head to make sure it’s good as well but I was happy to see my block is good at least.

I ordered a Fel-Pro MLS gasket and it’ll be here maybe tomorrow or Thursday, I’m gonna try and get my block prepped hopefully tomorrow or Wednesday and I’m gonna have my head done hopefully soon after but I’m not doing the head myself, so I’m not sure on that rn, but I’ll be at the beach next week so no work on the dsm until I’m back, maybe things will work out to where I can get it all done by Friday before I leave and I can have it back together to see how it runs then. Fingers crossed but if I have to wait then I will.

Also funny story, the dude that did all the stuff to the car(who the guy I bought the car from bought it from) has a yt channel and he made a video about the car. First right off the bat he called the car a 1989 eclipse then he started talking about the car, he said it has a stage 4 clutch, which it doesn’t, he said he “rebuilt the motor”, “put new gaskets and seals” which there is absolutely no way maybe a new vc gasket but that’s it, he said it has “LRP” head studs which they’re ARP head studs so that kinda confirmed that he didn’t actually do the work that was done and it was his dad and I guess he did the work that was messed up. In the video the car had a maf sensor on it and some sort of other manual boost controller on it, so I’m assuming he just went in and pulled stuff apart I really don’t know, I tried messaging him but of course he didn’t reply.

Still waiting on money to work out for me to get everything all done but I’ve gotten the block almost prepped, I need to flush the cooling system and finish polishing it but it looks a lot better than it did, I’ll post the pics. I’m hoping to have everything I need within the next two weeks but we will see. I hate taking so long in between doing stuff but sometimes it’s gotta wait, sadly.

Alright update for you guys, got the head back from the machine shop today and I was surprisingly informed that the head had been welded at one point, but I asked and the machinist said it was good and will be fine, he did a pressure test before he did anything and that went perfect.

I’m hoping to put the head back together tomorrow and get the head back on the car tomorrow as well, if everything goes to plan. Only bad news really is the CPS broke so I had to order a new one which it wasn’t even plugged In to begin with bc god knows where the plug is, I still haven’t found it yet. Not sure it got cut up or chewed up by the belt or something because the plug from the sensor is damaged so I’m wondering if the other end broke or he cut it, either way I need to get it fixed asap.

Other than that the DSM will hopefully be alive by Sunday. Fingers crossed.
