StewCrew Posted January 14, 2013 Author Report Share Posted January 14, 2013 Launching the car was awesome Cold idle made the car feel like it was going to eventually shake all the interior loose, and it made the B-pillar resonate at over 4000rpm. If it was me, I would probably run a set of very stiff fail-safe polyurethane mounts (ones that will not fail catastrophically) along with the reinforcements and replace the mounts as needed. They are easy enough to change and are a better "weakest-link" than the subframe itself. That is just me though. I am not as hardcore. Actually poly mounts with reinforcements doesn't sound like a bad idea at all. Almost perfect actually. I don't want the inside of my car to resemble an earthquake, which is what I've been reading lol. Either way, can't seem to go wrong with the subframe reinforcements. And with brand new mounts I wouldn't think they'd have to be changed too often. Quote Link to comment Share on other sites More sharing options...

And with brand new mounts I wouldn't think they'd have to be changed too often. I run OEM rubber mounts for the engine + trans. I would say I probably gave the car a good 10-15 hard launches, 2 hrs of track time, and a handful of slidey corners this last summer and they are holding up fine. Clutch-kicks are another story. I don't do clutch-kicks but I think that is where OEM mounts would get really angry. If my OEM mounts last are able to last 2 or 3 summers between replacement then I will be satisfied. I do know that Bimmerworld sells a stiffer rubber mount that I may try next time. I absolutely love the sig pic btw! Quote Link to comment Share on other sites More sharing options...

Many clutch kicks and hard high revving shifts are in store. Last thing I need is for a mount to rip lol. And thanks! It's actually going to be the "December" page for a British drift calendar...

Earl Posted January 15, 2013 Report Share Posted January 15, 2013 I'm getting all poly bushings for my rear subframe from a place over in Sweden (I think it was sweden). They're bushings are a phenomenal price and it seems a lot of guys around there love them. Quote Link to comment Share on other sites More sharing options...

StewCrew Posted January 15, 2013 Author Report Share Posted January 15, 2013 (edited) Something wrong with that?!?No disrespect Rev Sharpton, and imma let you finish, but I had one of the blackest oil pans of all time Do you have a parts washer? I need to get my diff cover cleaned up and dont feel like scrubbing for an hour. I may end up taking it to a coin-op carwash. We have a parts washer, a sandblast cabinet that isnt set up yet (), and my favorite.. wire wheel attachments. Which I did my oil pan with. Degreaser and wire wheel, which only took about an hour or so? The hardest part were the grooves. Youre welcome to bring that diff cover over any time. Except tomorrow. But any other time works.

StewCrew Posted January 15, 2013 Author Report Share Posted January 15, 2013 It was bound to happen sooner or later... and it has happened now. I am stuck. How do I remove this pulley/balancer doo-dad? One of the major points of this tear down was to replace this timing cover seal because it leaks. This is the last thing to remove before I attempt to put it back together, and Im stuck. Haaaalp Quote Link to comment Share on other sites More sharing options...
need4speed1299 Posted January 15, 2013 Report Share Posted January 15, 2013 (edited) Lock the crankshaft in place and use a breaker bar and cheater tube/lead pipe on the center nut. Edited January 15, 2013 by need4speed1299 Quote Link to comment Share on other sites More sharing options...

B C Posted January 15, 2013 Report Share Posted January 15, 2013 On my E30 I put the car in gear, applied the park brake and used a breaker bar with a cheater bar. On my Camry I let the breaker bar wedge against the ground and used the starter motor to spin it off. Obviously these options dont apply for you in this case but be creative. I personally would probably get a steel angle (decent size, maybe 1" by 1" with some good wall thickness and about 3ft length. and drill 2 holes in it to where you could put the flywheel bolts back through it and secure it to the tail end of the crankshaft. Then have a friend hold that as you remove the nut on the other side. I would avoid wedging anything internally such as a block of wood between the crank and block since the wall of the block could break-out, and I would refrain from holding the crank still by anything that is applying force to the pistons or connecting rods (such as inserting a wood block in the cylinder, resting the block upside down on the floor and having an obese friend sit on the block). Torsional reaction loading on the crankshaft is the safest bet. Quote Link to comment Share on other sites More sharing options...

Every single post I have read says to "put the flywheel locking pin in at TDC to hold the crank in place" and I'm like -_____- I think Im going to go with the angle steel route because I think I have a bunch laying around somewhere. Not sure why. But if it works, it works. Does the crank need to stay at TDC while this comes off or is it fine if it spins a little bit? The last thing I need is to mess something up on this part of the motor. And need4speed and Earl, thanks for you inputs! Quote Link to comment Share on other sites More sharing options...

It sounds like there is a spot in the block for a pin to be inserted and lock the whole thing at TDC? Thats a neat feature that I haven't heard of before. My guess is that the pin is inserted and crank is held at TDC for timing chain/cylinder head jobs where they want to leave everything timed @TDC so that there is less work/potential for screw-ups upon reinstallation. Re-timing the engine when the cam and crank are off by less than 5 degrees is easy. When they are off by more than that, you may cause a valve-piston collision trying to rotate things back to TDC Quote Link to comment Share on other sites More sharing options...

Re-timing the engine when the cam and crank are off by less than 5 degrees is easy. When they are off by more than that, you may cause a valve-piston collision trying to rotate things back to TDC Well, theres a hole to put a "flywheel lock pin" through; which when the motor is at TDC it slides in place between two of the teeth holding the motor from rotating any more. My real concern is with the head. Im going to take it to Automotive Engine Rebuilders (because its literally 10 seconds away from my shop) and have them disassemble the head, clean it, lap the valves, check for cracks, ect. When they reassemble the head, do they put the cams back in already set up in TDC where the valves wont hit or is that my job to do that? I have no experience with head work so Im not sure what to expect, nor do I know how to reset the cams. Quote Link to comment Share on other sites More sharing options...
B C Posted January 15, 2013 Report Share Posted January 15, 2013 They wont align the cams with their respective timing marks simply because the cams will rotate to wherever they want to be due to the valve spring tension (without the timing chain to keep them held in position). So its on you to remember to line everything up to TDC upon assembly, check it, rotate the engine 360 degrees, check it again, rotate the engine by hand a few more rotations, then check it yet again.

wasnt m3 Posted January 15, 2013 Report Share Posted January 15, 2013 Like I mentioned earlier, I have all the tools, including the flywheel locking pin. I got nervous when puting my head back on after MLS gasket and ARP stud install and had a bmw tech set my timing. Well worth the $100 for piece of mind knowing everything there's not going to be any piston to valve contact. I can get you his number if you need it. He came to me to do the work.

I didn't use cam blocks (dumb.. I know) while taking the head off so I'm not sure how to set them. I'm sure it'll be fine and work itself out when I get there. All part if the learning process Like I mentioned earlier, I have all the tools, including the flywheel locking pin.

He came to me to do the work.I like this idea a lot. Yeah, send his number my way. Does he let you watch? I know some mechanics/techs don't like that. I'm all for paying someone to come do it as long as I'm able to watch and learn how to do it properly. I never believed people when they said timing your first time was intimidating, but it definitely is. Quote Link to comment Share on other sites More sharing options...

StewCrew Posted January 16, 2013 Author Report Share Posted January 16, 2013 Some more progress \m/ Started to clean to lower timing cover too. Taking a break for now. Making hip up a parts store and get some gaskets ordered for it to go back together Quote Link to comment Share on other sites More sharing options...
