Old Shaguar or Modern Aldi

Have you spoken to any other specialists or dothed your tweed jacket and gone on any jaguar forums ?

Descends into the usual pistonheads bollocks but some interesting stuff

It looks like you can just do the tensioners by the sounds.

It is worth looking up a few threads by the poster on Piston Heads, 'Jaguar Steve'. He is in the linked Piston Heads thread. He seems to know a great deal about the Jaguar V8 - he has posted quite a lot there on it.

 

It is sheepskin coat season for us old Jag owners.

any news, Mr Imp?

 

ready to have me collect it at cost and save you a world of pain?

I am considering booking it in to get the top tensioners done but may still do these here. Volksy is looking into it as we speak.

Apologies, I am not following you here (I am a bit hungover)? Are you wanting to buy it?

Righto chaps an update on this and what is hopefully a ailment caused by my own stupidity. 

 

Not long after I bought the car, I was bored one day and decided to change the oil. I looked at the manual to see what sort of oil it needed and looked at this chart:

 

 

0W30? How odd I thought, never even seen oil like that before. Quick look on the Halfrauds and Motosave websites and it looked like I was going to have to spend about £100 on oil if I wanted to change it. Cheebus! Instead I had a look round the garage and I had more than enough 5W30 to do the job and it says that's okay. Okay its in cold temperatures but its nearly winter now so it will get colder and it can't do that much damage, can it?

 

Roll forward to December. I can hear a rattling in the engine and the posts above. Volksy came over to mine at Christmas and had a look at the car when we were having a fag outside. He suggested changing the oil before I did anything to the chains and tensioners which I drunkenly took on board as he thought that it could cause the problem.

 

It was not until a couple of days later when the hangover had finally cleared that I remembered the conversation outside on Christmas day and I decided to do a bit of research. It seems that early XJ8s have tensioners without springs which rely on oil pressure to provide the tension which is why you sometimes get a short rattle on startup until oil pressure builds up. This had always happened on mine but now the rattle was pretty constant on idle.

 

Therefore I decided to change the oil again, instead putting in the correct 0W30 oil. By doing this is seems to have cured the rattle. I can only assume that the 5W30 was thicker on startup which resulted in a longer time to reach optimum oil pressure. 

 

Now this leaves me with a couple of quandries.

 

1: Why was the chain rattling when it was warm? Its not doing it now but surely the 5w30 and the 0w30 run at the same temperature when warm?

2: It seems that the fact this happened at all means I do need the tensioners changing as I have the old shite ones so I need to save up for them but will waiting mean I might cause damage letting the problem come back. Does Mr Visa buy them for me?

 

Still, its better than where we were the other week.

Getting in to a big Jag would be an occasion every time. Audi's beginning with A are soul-less.
