2000 s70 non turbo...head removal and timing

Postby jfife83 » 17 Dec 2012, 19:54

When starting the engine the timing belt tensioner broke and the car didn't start, but did seize on one of the cylinders. Obvioulsy taking the timing of the pistons and camshafts. I am removing the head and sending it to the shop to be checked and valves fixed on that cylinder. My question is when putting the head back together how do I reset the timing of the pistons and the camshafts? Want this to be correct (obviously) so I do not cause any damage to the repaired head/valves. Any help would be greatly appreciated. Also, Tracystruesoaps head gasket tutorial is phenominal and after I complete the repair I will be making a donation.

Your car has VVT which is different than the pre '99 cars. There are some video's that were recently posted that may help.

As long as you don't remove the T55 Torx bolt that holds the CVVT hub to the camshaft or the sprocket where it bolts to the hub you can treat this just like a timing belt change once you get things back together.

While the head is off you want to time the crankshaft to its timing mark. In the case of most of the later models it is actually two notches on the camshaft sprocket and you center the timing mark on the oil pump between the two marks. Here is a good picture of what a properly timed crankshaft should look like.

Once you get the head back you can follow the other procedures for lining up and holding the camshafts for re-assembly. There is a wide variety of homemade tools documented in the repair database and in the you tube videos that were linked from here:

viewtopic.php?f=1&t=53115

In my case I wound up buying the kit for $180.00 on eBay. They are a very nice set but that was some severe wallet pain.

Once the cam cover is back on you can re-install the timing belt, tighten the tensioner, remove the cam locking tools, and rotate the engine clockwise two revolutions. From there continue to rotate the engine another 90 degrees in the clockwise direction and then back the engine up 90 degrees, counter clockwise, until the marks are back lined up. Remove the timing belt and re-install it, you will need to rotate the exhaust sprocket somewhat to get it back on the marks. At that point your CVVT pre-load should be set.

Most of the pictures here are of the non CVVT models, you have different timing mark locations. Yours will be more like these.

After the belt is installed and tensioned I leave the cover off and check the tensioner again after the car has run for a few minutes. You will likely need to touch up the tension.

Looking at mine before pulling the cam cover the marks are at 6:00 and my crank is on time. Should I just move the cams to the 12:00 timing mark? Also, what cylinder should be in its top position when reassembling?

You turn the crank to the mark, don't worry about where the pistons end up.

So cvvt will take care of the rest as long as all timing marks are in the correct place?

Once the head is off set the timing mark on the crankshaft, that is more or less #1 TDC but don't worry about being spot on TDC. The timing mark is what needs to be lined up and its location takes presidence over the piston position.

When the head goes back on is when you will need to line up the cams. Don't try to rotate the cams without the timing belt being on and the timing being at least close. For right now, after the belt broke, the timing is all out of whack but you can deal with all of that after the head is removed. At this point don't even try to re-set the timing with the head still on.

I wish I had a real quick and easy trick for removing the dust cover, I don't.

On my engine I was replacing all of the seals on the replacement engine but not removing the head and I wound up destroying the cover in the process. Fortunately, it was only a few dollars at the dealership. Since you are removing the head I would just leave it in place until you get the upper cam cover bolts loosened up and at that point it will essentially just fall out.

The picture is interesting, I thought the NA versions had the CVVT on the intake cam but VADIS showed it on the exhaust. The procedures for setting the CVVT preload should be the same in either case.

Ok...cam cover is off....the exhaust cam in the pic doesn't have a gasket on it and was leaking into the dust cap....good thing this happened .....would have never known ...
When cleaning everything while head is at the shop should I use gasoline and a toothbrush? I actually am very mechanicaly inclined, just never got this deep into an engine.

I use kerosene and let things soak before I go after it with a plastic bristle brush. If you are sending the head out to a machine shop they will clean the cams and the cam cover along with the head for cheap. I think they used heated parts washers and things look brand new when they are done with them.

It is interesting that you didn't have a seal on the rear of your exhaust cam. My XC engine with the low pressure turbo engine didn't have one behind the cap on the intake cam either. I added it when I replaced the other seals.

Your next hard part is going to be getting the head bolts loose. They are very tight but you don't want to go after them with an impact wrench or use a jerking motion to break them loose. If the bolts break the job will be much harder. I use a 1/2" breakover bar and 4 ft. pipe with a fairly steady pressure to get them loose. Once the bolts are off you are home free.
