P6 2200 TC electronic ignition.

Hi Pat

car has stand stil for a while, some years, I have let run the engine hot and did not see the oillamp get on, after start it go out quickly, some test can I do
like in cold starting and set off, lamp has to stay out some time. maybe spring of oil pressure is not oke, or the timing chain tensioner, chain do sing
a musical song, (high irritating tone when idle) I did read here that this is a wear chain? maybe the oilpressure is a reason, I do go look at it tomorrow..

here is the engine running.

do someone now what is behind this, see picture in white cirkel, I have removed this and it just hollow
it needs not a spring for example?

That is the upper timing chain tensioner cover, the tensioner is located at the bottom end of the hollow bit and should have a bolt in it. You can remove the bolt and insert a 1/8 inch allen key to retract the tensioner.
 
There is no bold in it. just a hole, but it stay dry, no oil coming out, to is is a bearing where a bold can put in, oke.

I have test the big end bearings, it looks she are good, but oil pressure is low, I hear this when engine idles, it sound some
hars.

I have ordered a workshop manual on ebay, I do need it.

That is not right.

The cam chain tensioner consists of a piston a spring and a rubber slipper. The rubber slipper bears against the chain taking up the slack. Oil pressure forces the piston and hence the slipper against the chain. The top cam chain tensioner oil supply is via the small bore pipe to the banjo fitting above the access plate. There is a small drilled hole in the piston which also passes through the slipper allowing oil to drip through and lubricate the chain. The bolt which is missing is only there to provide access to allow an allen key to be used to wind the tensioner off the chain for maintenance. It must be refitted before running the engine.

If the bolt is missing there can be no oil pressure build up behind the tensioner to force it against the chain hence cam chain noise. This may also be the cause of the general reduction in oil pressure.
 
I have the bold for in the tensioner, I do not understand why the tensioner do not press when bold is out, because then oil
have to get out of there when bold is missing, this do not happen.



thanks

I don't know what type the bolt is probably UNF ( F=fine pitch ) perhaps 3/16" or 1/4". Take a bolt off something else and try it in the threads. Perhaps someone has one off the car to measure or harvey may know. Its only short though and has a copper sealing washer. If you can get a bolt with the right thread it can be cut down to fit.

The allen key is 3mm. Turn only CW. Turn CW to move in towards the chain. Turn CW again to move away again etc. If you turn it CCW the tensioner parts can come apart and fall into the sump. Stuff rags or paper towels below the tensioner to prevent parts falling into the sump. Prise out the circular bung at the front of the engine so you can get at the side of the tensioner.
 
So you mean that turn only CW get into the chain and then it losening again? by just turn in the same direction?
strange but thanks for preventing a disaster.

Oke I have the spring out, as I say it is very weak in my eyes, normally you have to press te bold to get it in again
these going out easely be hand and can press the spring with two vingers, plunjer was not stuck, it is a long
one, I do not now of there are rubber rings or something in that.



I can put spacers in this nut get more spring tension and test what it does with the oil pressure, if it rises than problem is here
if not bearings are suspect.

Tensioner do not tension the chain whatsoever, I have block the oil and did start, just the same noise so problem is that bold.

Well I have strengtened the spring with washers, the pressure is now raised to 50 LB not complete warm engine, and 48 LB
when idle 600 rpm.

this is 10 Lb more then first, but I did thought the spring did not regulate the pressure but is only aktive as over pressure protection?

little strange this way.

see pictures, engine do idele more smooth now, not as raw anymore but I have no working upper chain tensioner because I miss that little
bold.

Normal oil pressure on a 2200tc is 50-55psi just slightly right of centre dial. That looks low. Could be main bearings or big ends which can be replaced by removing the sump. Could also be a defective sender or gauge. Might be worth removing the relief valve and stretching the spring to see if the pressure comes up.

This did work :D have now 50 psi so not bearings because if she are the cause then pressure do not go up with more spring tension.

the upper chain tensioner do not press, chain makes noise because of that, I do also miss the filter under the banjo bolt.

tensioner removed, no bold so big hole, but er do not coming oil out of that, but shout do happen, banjo give plenty oil but maybe no
pressure, otherwise oil has to come out of that hole bahind the tensioner, oil supply opening has a very smal hole in it, so pressure
has needed to get oil in. I do not now or the bottom tensioner has the same problem, I do not now if she share oil supply and or the bottom
tensioner has problem that bold was out like the top one, remove the bottom tensioner is a bigger problem.

I go try now if I can see debris in the oil supply channel of head.

But hee, I get out of topic, maybe saomeone can move this to a suitable place like oil pressure problems, thanks.

solved!! debris in the small hole was the problem.

I think even that this is common, I have no oil filter there, it is gone. people who hear high sing tone,
proberly this is because of lack of chain lubrication and no tension because of blokkage, justa idea
whem you hear that to remove the cap and see if the is oil on that upper chain.

a big mistake of the makers of this engine is to get oil to upper tensioner before oil filter, hence the
filter under the banjo.

Oke I have drive the car until warm, oilpressure then go down to 30 psi 2.1 bar, when give more rpm it do not rise
normally it has to, so bearings can de a problem or the oil who can be very old or possible wrong, this because
the old owner has not much knowledge about this car..

Well I have solder my electronic ignition design, it is equipped with a modern ignition mosfet and
a input mosfet for
reliable working, it has also some resistors for keeping the points clean (100mA current).

it can also work without points with other means like induction.

 
Here I am again, still alone! oke, I hear some nocking from engine when accelerate, oilpressure is slightly above 50 psi when cold and
drops to 30 a 40 psi when warm, I did see engine get not warm enough, just end of white bar.

power of engine is oke, it runs well, I go change the oil, because there was a gasoline problem like flooding of one of the carbs
if I remove stick to control oil level the oil drips off even when cold, so is quite thin.

chain sound is gone, also that hight pitch sound,.
