christ...can this 240sxmech guy get banned? The guy probably cant change his oil and he thinks he's hot ****.

y'know, 5 years ago I didn't know what TDC stood for. Now I'm the guy who people bring their cars to when they need some work done, none of us can afford a shop. How did I learn? By mucking around, breaking things and fixing them again, and with help from people who did know more. That's the purpose of a forum like this - because we aren't all born in an engine bay.

It's good to see all of the helpful posts here, but there's one person here who I'm sure goes home in a stock civic that really needs to find another place to vent his preadolescent angst.

So, thursday, welcome. And best of luck with a very nice car you got your hands on. I drive a 90 SE, currently in my garage waiting for me to rip the engine apart...and love her to death.

and bone_stock, that animation in your sig is hilarious.

yeah! And jesus freakin christ, when will they stop bleapin out the cuss words. Oh yeah. Someones avatar looks like a double rubber *****-s-s-y.

But seriously. I know what you mean. I'm not a mechanic, but very mechanically inclined. I worked on aircraft for 6 years and I have not timed my own engine yet. No need to so far. From what I have seen, most people on here are cool dudes with years of experience, so I can use the help when the time comes. I'm a big fan of H8tred!

The sad thing is, according to his profile he is a 29 year old mechanic and engine builder. His words and actions are those of a 4th grader with mild mental retardation.

Yeah, I am the same way. Last year I knew nothing. I spent alot of time on the forum reading and trying stuff myself. Now a year later, I do all of my own work, and have helped people swap trannies and clutches, and am currently in the process of swapping out a blown motor.

theres a few ways.

you need to find a way to hold the crank stable .such as taking out the starter and holding the flywheel.puting it in gear with the ebrake UPP.

or simply find a high velocity air impact

i have a auto trans. (A/T) i think im going to hold the flywheel with a vise.

i will post more video when i get it done. but i think i know what i did wrong, when i set the cam and the crank at TDC i think i put too much slack on the driver side there for it was always 1 or 2 teeth off . i just got the new valve's put in, and cant Wait to hear it fire . thanks so much for your guys help!!!!

You can take a small length of chain, bolt one side of it to the flange where the bellhousing bolts up to, and bolt the other side to the flexplate somewhere. I am not sure what a flexplate looks like, so I can't suggest a specific place.

Dude Nico owns. Theres so many cool people here, the good completely outweighs the bad. Where ever you go in life your going to deal with simple people like Mech, but you gotta let the things morons like that say roll right off your back.

I mean, out of how many people helped you in this thread, only one decided to act like a high schooler and make an *** out of himself. On most threads however that wont even happen.

240sxmech : NO ONE wants to hear that garbage here. Didnt your parents teach you if you dont have anything nice or constructive to say then keep your mouth shut? I promise you, keep flaming and your days on NICO will be limited. However, because were all ignorant why dont you just pack up your things, we wouldnt want to bring you down.

Well if it's a SOHC, not much to really do at the head to maintain it being at TDC.

Make sure the tensioner is off, and then loosen the cam towers. This will keep the valves from opening/closing while you rotate the cam or crank to the proper position. Rotate the keyways to the 12 o'clock position on both the cam and the crank. Reattach the chain, tighten down the cam towers, and put back on the tensioner and pull the pin to put the tension back on the chain. This is assuming you've got the basic of matching the punch mark on the cam and crank sprocket to the differently colored link on the chain. If you need help on the orientation of the oil pump/distributor post back.

I had to replace the exhaust valves and now I'm at the point where I want to get the timing perfect the first time, instead of adjusting the chain one or two teeth and starting it up to see if it's timed right. So, can I pull off the crank pulley without removing the crank bolt? And if I can will I be able to take the timing chain cover off without removing the bolt?The reason I ask is because I do not have the tools/equipment to remove the bolt and set it back to the proper torque. I'm afraid if I put a vicegrip on the flywheel I will damage the flywheel in some way and I don't have a chain to hold the flywheel. I tried putting the car in drive,reverse,park and rolling it back until it locked, but the engine still turns when I turn the bolt. That's why I HATE automatics. So I think it would be in my best intrest to leave the bolt alone, but if I could get the timing cover off without removing the bolt that would be awesome.

That seems highly impossible.
