One other very important point that s not in all the online instructions: Remove your fuel pump or fuel injection fuse once you are all done with both sides before you crank the engine. Then crank for 5-10 seconds before repalcing the fuse and starting the car. This gives the new tensioners a chance to pressurize with oil. If this is not done, you may jump a sprocket(s) and lose your timing or even damage the engine.

There should be a position where one or two lobes might be just touching, but not putting any significant pressure on the valves. Take out your spark plugs if necessary to make the engine easier to turn.

You should inspect the Chains to see if they are not too damaged to be used. The damage would be on the Edge of the Chain that rode on metal shoes of the bad tensioners.

As long as your chain was tied on you are fine timing-wise. The chain may not be tight until the system repressurizes...that is why it is so important to crank first without fuel before starting the engine.

I too am a little concerned about chain wear given the wear on the tensioner metal plate.

Default Change looks ok I believe

Once and awhile there a spec of shinnyness of bottom but very minimal. Chain looks sound. If it went any further it would of been disaster. Lets hope the best on other side. Havent got there yet.
What is torque on tensioner bolts and cam caps?
Thanks for your pro guideness. Maybe my Confidence will soar on #2. It is nerve racking.

Tensioners: 10 - 14 Nm

Cam Caps: 9 - 11 Nm

Cam covers: 9 - 11Nm

Smile Foot Pounds?

Foot Pounds? is that 10 ft pounds tensioners and about 7.5 ft pounds cam caps. I got new 6 X 30mm on tensioner bolts. Long Enough? Thanks

Nm = Newton Meters

Thats about right on the conversion to ft. lbs.

If the new bolts are slightly shorter than the old ones they should be the correct ones.

Default Gasket set VS50724R

4 last questions

I got a gasket set Felpro VS50724R. I understand the basic gasket but where does al the litlle washer like round ones go?

On bottom of screws of valve covers. Surely not. How do you hold them while installing. Sorry to be so stupid.

Thank God this job is on the mend.

What about turning it over now wth plug wires off?

That way I can view things and correct if something looks wrong. I know oil will go everywhere. Will it throw engine lights?

Thanks to every one who said "Don't even start her until you change tensioners".
What about the people who say "We are wasting or money if we don't spend the $1500.00 to change all the timing chains, tensioners and guides"?.

Are those guys greedy service from Jaguar shops who can't stand guys like us venturing into thier domain?

I'm glad you listened to us. A lot of people would have just crossed their fingers and hoped for the best. You've just save your car, and saved yourself thousands of dollars.

The Felpro gasket set is not correct for the '98, that is for later cars, starting in 2000, I think. You are going to need to get the valve cover gaskets and spark plug seals from the dealer....that is the only source for your year.

The small washers are still the same though...they go on the valve cover bolts...you will see the old ones if you take a close look.

Do not crank it unless you have the valve covers on at the very least or you will have an oily mess under the hood.

One check you can do to confirm that the timing is correct is to rotate the engine until the flats on the camshaft (near the front) are face up. The flats on the two camshafts should be in the same plane (you can put a strightedge over them).

As far as a full timing job goes, it is good preventative maintenance on a car of your age, however, a failure there will likely not ruin your engine. Because of the risk of engine damage, the secondaries are more of a 'must do'.

Wow. You were ready to fail at any point. The next ignition cycle could have toasted your motor. Glad you came here, if you waited a day or a week or an hour, things might have been much worse.
