Another Rn + 20G, My 'build' Thread


Recommended Posts

Unfortunately I don't have a '98 housing. I would have just drilled my '96, but it had no real provision for it.



Per Alldata they are different.

I.E. 32F - 5740Ohm (99) vs 7300Ohm (98)

Damn... I could find a thread adapter, but I doubt locally. Maybe I'll talk to my machinist.

I flushed a mixture of MMO and Kerosene through the oil channels to try and remove any particulate matter that may have gotten in when the head was off. I left the drain plug open and just let it run through. Based on the before and after it seemed to work pretty well.

Yes, need to put on the sealer on the top of the head, or on the top cover, and be sure to put start up lube on the cam lobes and the lifters, don't want them galling because you turned it over without any oil on it. Also need the Volvo tool eventually to set the cams to the right position when you are ready to put in on the block.

Well, looks like I fucked up. The intake cam was 180° out when I tightened the valve cover. There is no way to turn the cam back to the correct position without taking off the valve cover, is there?

Is there a possibility that I bent a valve by tightening the cover with the intake cam 180° out?

But wouldn't that force down a valve, possibly one that I don't want down and end up bending it?

EDIT:

Alright I just turned the cam to the correct position. I wasn't really sure if I could turn the camshaft without pushing down the wrong valve. I didn't run into any resistance while turning it so I guess it'll be alright.

Just so you know for future reference, if you rotated the cam and felt a valve kiss the piston, rotate the cam back slightly and turn the crank slightly, you can keep "shuffling" them until you get the cam in the position you want, you wont hurt a valve by turning the motor over by hand, as long as you go slow and feel for resistance you will be ok, if you really want to be safe just pull the spark plugs then there is no guessing wheather you are feeling compression or a valve, but honestly its kinda hard to NOT know when a valve hits the piston.

btw, make sure you install the cvvt hubs properly, per the manual. They can be a real pooper sometimes =p

So..... did you install the forward cam seals from the back end of the cam to avoid removing the hubs from the cams? I don't see the seals in the pic you posted.

The reason Volvo set the crank marker where it is for t/belt install, is that you cannot hit the pistons with the valves through any part of their rotation, it's not even close to TDC.

I removed the hubs to put the seals on. I got it timed up and rotated the crank a few times and everything was gravy. Hopefully I can turn the key tonight...

Good to know about the crank position. I wasn't really sure if turning the cam without the crank could inadvertently bend a valve, but I'm sure I didn't.

Well I stayed up late in the hopes that I could turn the key tonight, but found I had a big coolant leak. When I got the new head the lower coolant bolt was bent and had bunged up the first part of the threads. I cleaned it up with a tap and thought it would be fine. However, when I put on the bolt with the head on the car the bolt stripped.

This is probably one of the worst positioned bolts on the whole engine to re-tap. I honestly don't think I could drill and re-tap it with the head on the engine or with the engine in the car. So I figure I have 3 options (from easiest to hardest):

1. Put the bolt in with a little JB weld, tighten it as much as I can and let it harden. After about 5 hours go back and re-tighten the bolt and see if I can get some extra torque on it.

2. Try and put a helicoil in, although I've never used one so I'm not sure if I'd have to re-drill the hole.

3. Get a right angle drill bit and tap for a larger bolt.
