I had to clearance it myself since I've also had the crank machines so clearances will vary from a completely stock crank. And the oil is getting changed after the motor break in anyways, so I'm not too worries about the particles. Manaed to finally pull out the old motor.
Second time I've done it. Motor out in less than 3 hours. I prefer doing it this way because I can drop the transmission and motor as one piece, and put it back in as one unit as well. Saves me from having to drop the transmission first or having to align the transmission afterwards with the motor in the car. I like doing as much work as I can on everything outside of the car.
FYI, and I would have thought you knew this already, but if you drop the front cross member, you can pull the box and engine together. Not saying it's easier, just saying it can be done. Obviously all the same prep work needs to be done.
You can pull the engine with box attached without dropping the cross member. I did it the first time my motor came out.
I thought you can only do it this way if there is more than 1 person to assist. You get the other person to stand on the box to increase the angle the box and engine come out so as to clear the radiator bar.
It's much easier just dropping the motor and transmission through the bottom and just lifting the chassis up on a lift haha. I'm lazy I know about dropping the crossmember for more room to work with, but this is less muscle work. I'm most likely going to reinstall the motor and transmission in the same manner. I'll just be slipping the chassis on top instead of lifting the chassis off haha. Got some work done. Did some small amount of work on the old motor and installing some new parts. Evidence of blow by :/ The manifold was spotless before I put it on the motor. PCVs were also dripping loads of oil. Plugged up the PCV ports since I'll be running a catch can set up. Also opened up the TB openings on the plenum. Smoothed out the openings as well. Bored out TBs painted matte gunmetallic with new black hardware And that's it for today. Tomorrow I plan on removing the timing belt components in preparation for pulling off the heads.
Did some work taking apart the old motor. Pretty much everything timing belt related is off. (my Z [photobombed me, lol) The Holy Grail of thermostats, Billion. Such a reliable piece. Decided to paint the VTC gear cover and 4-bolt washers matte black to go along with my BDE units. Gonna buy some black hardware as well to get everything matching. Everything removed. All nuts and bolts sorted according to area in baggies. Quick shot of my exhaust set up. Going to eventually ceramic coat the test pipes, and also modify the h-pipe and turn it into an x-pipe for more NA rasp. And possibly some more power, lol. This is what I had in mind. Move the resonators closer to the bottom flanges, and put the crossover piping afterwards.
More progress. Just about ready to yank the heads off. Found more evidence of oil blow by :/ Pulled the plugs too. What do you all think? About maybe 10k miles on them. Maybe. Weird wear marks on the cams, but only on the closed section of the profile. So odd. The ramp up and ramp down sections are fine though. Also pulled the pump out of the tank. Going to install a TT one to handle the extra flow needed for the E85 tune. Siphoned the gas out as well. It helps that the tank was completely filled. Helped in keeping moisture out and preserving the gasoline. Tomorrow, the heads come off, and they get disassembled, ready to go to the machine shop.
Soooo, I guess the motor was flat out guzzling the oil :/ Pulled the heads off finally and took some pics. Needless to say, the heads are off to get hot tanked for cleaning, lol. The intake valves are also being replaced as I believe these are the softer 90s intake valves. Some preventative maintenance.
Well, got the news from the machine shop. 6 of the oem intake valves in one head are toast. and 2 of the replaced intake valves on the other head are done as well. The fix? ordered some Supertech 0.5mm oversized SS intake valves to handle the abuse and help bring in a little bit more air into the motor
Damn intake valves. They were the reason for my cold non-start issues on my previous Z. I have manley SS valves in my new engine
Haha, no kidding. Who knows what killed mine, but whatever, problem solved. Got a few more supporting mods for the car. Picked up a TT fuel pump for when I do the E85 tune as the NA pump might not pump enough for E85 use. Also grabbed some Injen intake hardpipes. Already shaved off the unnecessary nipples. Now I just need to get it powdercoated textured black. Also grabbed some stock TT injectors to hold me over until I get some 555s for E85 usage. The TT injectors should work just fine for a regular tune on 91. Heads should be done some time this week. __________________
Thanks. It's slowly coming together. Small progress is progress https://www.youtube.com/watch?v=9giGvXlARdY quick video of the bottom end in motion. So smooth! Also installed the motor mount brackets and BDE motor mounts. And cleaned up the AC compressor bracket and installed the compressor. And cleaned and installed the alternator bracket. I still need to clean off the alternator, so it isn't going on just yet. Also got a shot of my new high pressure power steering line. No more leaks! As a bonus, a quick shot of my old reliable motor that suffered it's Viking death. That's where rod #2 used to be. Pretty gnarly haha.
2 out of the 8 bad intake valves had recently been replaced. That's what confused me. but whatever, the heads are ready for pick up. Pictures will come tomorrow.
Small personal WPC demo http://www.youtube.com/watch?v=PBJ8mhx6lQo First part shows a crank sprocket on a stock crank snout. If you've ever installed or removed a crank sprocket, you know how much of a pain they are to slide on and remove without grease. I sprayed WD40 here. Second part shows how easily the sprocket spins on my WPC treated crank. I had to install the crank bolt and washer in order to keep the sprocket from flying off! Pretty amazing to see in person. Can't wait to see the results of the massive reduction of internal friction with the complete crank paired with the wpc treated rod and main bearings. How exciting! Took care of some smaller stuff as well while I wait to pick up my heads. Installed the Ramey idler stud. Installed the det sensor. I'm not a fan of relocating it. Thermostat housing and related piping installed as well. So glad the threads in all the holes are perfect. Cleaned up the PS pump. This will hold me over until I get my spare one rebuilt. Planning on WPC treating the internal, and converting the fittings to AN in order to run full SS lines for my power steering. Cleaned the alternator as well and installed it. So much better than before. It was encrusted with PS fluid grime :/ New dowels The set up for my auxiliary oil pressure sensor. BSPT to NPT adapter. Relocated the stock unit back more. We'll see if I end up keeping it there. Definitely not permanent. Fun stuff. Heads tomorrow! For sure!
