Moderators BarManBean Posted January 14, 2016 Author Moderators Share Posted January 14, 2016 OEM clutch comes with a mark on the clutch cover that should be installed 120 degrees off from mark on FW. Sometimes the marks are missing or hidden by dust so it helps to mark the clutch cover to the FW with a white paint marker or similar. Aftermarket clutches do not have such balance/alignment marks, and should usually be balanced by a machine shop anyways (usually while getting the FW resurfaced for a new kit). I have seen some reputable aftermarket clutches as much as 40g out of balance (1g or less is the target for street performance car). OEM clutch here. So...hope and pray that I can find the marks on both the pressure plate and the flywheel? Otherwise...I'm buying a new clutch?

Underdog Posted January 14, 2016 Share Posted January 14, 2016 Otherwise you can try and guess by matching any corrosion/dust and make a mark, or just get the kit balanced if you are really worried about it. The Crimson Dynamo Link to comment Share on other sites More sharing options...

boxkita Posted January 14, 2016 Share Posted January 14, 2016 I hope you marked the clutch assembly so you can install it in the same position. Nope, I did not. Please advise?

xt2005bonbon Posted January 14, 2016 Share Posted January 14, 2016 I was thinking... Since you'll change the valve cover gaskets, you might as well check the valve clearances. It'll take you 15mn for both sides. Just make sure you have a good quality feeler gauge. Also, how many miles do you have on this engine? Link to comment Share on other sites More sharing options...
xt2005bonbon Posted January 14, 2016 Share Posted January 14, 2016 Also, if you decide to do this, I would check the clearances with the timing belt on. Link to comment Share on other sites More sharing options...

Also, how many miles do you have on this engine? 88k miles. I'm hoping to perform a compression test while the motor is on the stand. Will need to rig the starter back up and the battery, and the engine will obviously be cold, but should give some confirmation that everything is as it should be. I expect no issues though.

xt2005bonbon Posted January 14, 2016 Share Posted January 14, 2016 I see. Although if a valve has tight clearance, it may not show up in the compression/leakdown results on a cold engine. Usually, it shows up on the leakdown result on a warm engine. This happened to me: I did a leakdown test cold and had 2.5% leak on #2, which is a very good result. And yet, I was having roughness when warmed up. And yep, one exhaust valve had no clearance at all. I would still vote to just check them. It's very easy once the VC are off.

Good excuse to pick up some feeling gauges Do yourself a favor and buy metric guages. the conversion from sae to metric to sae is enough to ruin the heads. Test them all and post?

xt2005bonbon Posted January 14, 2016 Share Posted January 14, 2016 Everyone waits until the tb is off to do this. The numbers are different with/without tb. Actually I think it is wiser to do it with the TB on as it puts some pressure/tension to the cams and slightly affects clearances on the valves closest to the TB. If you recall in my thread, I did the measurements with and without the TB and did see some differences. The FSM describes how to measure the clearances with the TB on [see ME(H4DOTC)-26].

Moderators BarManBean Posted January 14, 2016 Author Moderators Share Posted January 14, 2016 I'll go ahead and make plugs / VCGs a top priority. Will check compression and valve clearances when the VCs are off. I may loosely bolt the VCs back in place and then change the timing, and recheck. I see no reason why clearances would change with a new timing belt, but we can see in the name of science / stupidity.

xt2005bonbon Posted January 14, 2016 Share Posted January 14, 2016 Hence my request / suggestion to do it before taking off tb. A lesson i learned too late I misunderstood your post then. sorry about that. I see no reason why clearances would change with a new timing belt, but we can see in the name of science / stupidity. You will see for yourself then . But really,as I said may only affect the cylinders closest to the timing belt (i.e. #1 and #2). Note though that I've only checked #2 and #4 with belt on and off, and saw noticeable difference only #2 really. See below. Here are the clearance measurements with the timing belt on vs. off. I only posted measurements for cylinder 2 since it was the only that had different clearances. So from what I understand, once I install the new buckets, the clearance should be larger than expected for cylinder 2 with the timing belt off. But once I put it on, the clearance should be fine. We shall see. http://legacygt.com/forums/attachment.php?attachmentid=211748&d=1435630541 Link to comment Share on other sites More sharing options...

Humor me...some more. Check all of them before you take off the belt, then again when its off and finally when its back on. And post results. The manaul only has values for 2 valves and only with tb in place. trying to set clearance with an unloaded system is mostly black art. As even factory has to do a final check manually ( subie plant worker posted process in my drama thread) Build my car Boxkita Track days Link to comment Share on other sites More sharing options...

Moderators BarManBean Posted January 15, 2016 Author Moderators Share Posted January 15, 2016 Also ordered spark plugs and a feeler gauge set. Nothing else tonight. I'm feeling fairly accomplished just getting the motor out. I think the weekend will be time to pull out all of the parts, gaskets, etc that I have lying around, make an assessment of what else needs to be procured, and come up with a game plan / sequence of events.
