I've all but finished my article on the X308 XJR- with only minor touch ins to do:
1998-2003 Jaguar X308 XJ8(R)- An under rated scorching luxury Saloon | Auto-Scape

thanks to some of our members for pictures...

 

To all X308 members, this is well worth a read!

 

nice writeup

 

very nice write up thanks for sharing

 

Fantastic read ... well done Sir!

 

please see PM for original content

 

Interesting article. Thanks for sharing it with us.

 

@ plums, you could have p.m'd that.......more fuel to the pedant tag.....I'm a teacher, and don't get hung up on it, numeracy and literacy are important to me, but I tent to take my students to one side for corrections. More manners and tact please.

You obviously haven't worked with engineers, we can't spell, we're more interested in numbers and results. Are you OCPD?

 

You are quite right. I will edit and pm. BTW, that's OCD.

Now, whether engineers spell or write worse or better than others ought to be immaterial when articles are written for public consumption.

 

WHen I worked in Germany as an Engineer- the head of Powertrain Doktor Fischer would be very pedantic about axis fonts and titles. He wouldn't let up and I believe he thought he was some kind of stubborn hero. He would rarely comment on the technical content of any presentation. It soon became apparent that he didn't understand it and the only way to gain power over his 'lessers' was this way.
It took Hyundai about 4 years to constructively dismiss him - 4 years of waist and mis direction. He then got a job for 6 months before being fired again. Last I heard is that he's now contracting for BMW on some exhaust heat recovery project.

Food for thought

 

nice article...I love my R1 option...nice to see it mentioned!

 

Whether content is of a technical nature or not, it is easier to digest when one does not have to puzzle over the mechanical construction of the content.

Also food for thought.

 

Good write up, thanks for your time

 

The description of the engine was fabulous! It would otherwise be impossible to find that sort of info online.

 

Hey, we know where to go if we need a proof reader, mind doing that for my PHD? know anything about lasers?

 

is this article still available anywhere? I can’t access the link.

 

Since last March 2020 I had not been able to get my 2000 X308 in for an emission test and not needing the car left it sit in the driveway covered.

had disconnected the battery, and some previously posts finally getting it to start and run this past summer briefly and driving before covering it and leaving it sit.

However while sitting the first time it formed a very large engine oil leak that I did not discover until I finally started and moved it for a drive which of course made the wife extremely happy to see.

So after moving and driving it around and restarting, and full IDS diagnostics to verify the ECM had some defective inputs, placed it on my lift for the winter, located an updated ECM, installed, programmed and verified full operation. While on the lift the source of the leak appeared to be the oil pressure switch so a replacement was sourced with some fresh filters.

Life happens, and I only today got to drain the oil which was not near as bad as I had expected, removed the oil filter, pulled the oil pressure switch and to my surprise notice a second sensor for the engine oil temperature (EOT). It was actually BOTH sensors leaking and had been slathered with RTV by the DPM. Removal of the EOT is a total PITA that requires a thin wall 19mm deep reach 1/2" drive socket or a 19mm split thin wall socket that has been opened up internally large enough to fit over the connector without touching the plastic.

Yes the two sensors are of course different wrench and thread sizes, only the start of the fun.


Black = Oil Pressure, Gray = Oil Temp The Dreaded Previous Mechanic has slathered RTV on the plastic to metal crimp side of both sensors apparently to seal off a previous leak. I did not discover the RTV until I removed and cleaned both sensors. Note the EOT has a unique "V" profile to fit into the narrow oil passage and still allow oil to pass properly.


Engine Oil Pressure sensor after a bit of cleaning, note the RTV at the plastic to metal crimp on the upper back side and some fell off onto the dish - there was a LOT of it before I cleaned it.

I'll edit later to add a photo of the EOT in position.
Upper EOT sensor needs a bit of finesse and a proper 19 mm deep reach 1/2" drive socket with the internals opened up to not interfere with the plastic connector or yes, it will leak again! With a new photo you will note that the Oil Temp sensor is precariously positioned very snugly above the oil pressure switch and the alternator bracket - very tight clearances and recessed too.

EOT superseded part number was LRA1600A which not surprisingly is NLS obsoleted, and possibly replaced with AJ810031 that I noticed has a different sensor face that may or may not fit properly n the not-so-deep oil passage. After a bit of looking I found a Ford replacement F5AF12A648AA that has the correct specs. I'll need to see how IDS see that EOT once installed.

A call to my local parts gal at JLR to verify part numbers and stock. In the mean time I've removed and degreased the cam covers, replace all the seals, replace upper O2 sensors, then maybe in another week go get a full car wash and finally go for an emission test.

Now I need a garage heater

 

Just painted the asteroid wheels steel gray color

 

Something wrong I posted my wheel paint job in another thread

 

I note my post on the oil pressure and oil temp sensors also went to the wrong topic, it was originally in "What did you do with your 308 today?"

@MODERATOR, I think there is a SQL error in the database
