New member, x308 possible engine seizure

Postby Firth_barge » Tue Jun 18, 2019 12:51 pm

Hi, I'm in Birkenhead, Wirral and have recently bought a 1999 x308 3.2 with 77000 on the clock. It is in great condition cosmetically, with hardly any rust anywhere on the bodywork and a very good condition oatmeal leather interior.

I had already heard about the nikasil problems with this model and the plastic cam chain tensioners and my original plan was to find a relatively solid, lowish mileage example as my first foray into jag ownership (my uncle had a 4.0 x300 xj6 that I used to love riding around in) and I was going to get it home and replace any of the suspect parts/inspect for tensioner replacements and so on, and learn a lot about the maintenance of this car, but after being properly warmed up from cold with no audible noises, I was driving it home on cruise control at around 60-70mph, had a low oil pressure light flash up very quickly a few times before a sudden loss of power and the dashboard displaying restricted performance. There was no knocking or rattling. Cue a 3.5 hour wait on hard shoulder of the M40 for the RAC and to keep it short we didn't actually get home until the next evening. (I bought the car in London) The recovery man wanted to rule out alternator before putting the poorly jag on the truck but he said it literally zapped his battery pack dead in seconds. Have tried another battery but with no change.

The car now clicks upon ignition turn which I think means the starter solenoid is getting power, however, I have no idea how much yet. Have removed and checked state relay and others. All seem to be fine.

Need to check the battery etc. with a multimeter and do a drop test at the starter but seeing as the engine won't crank by hand and I can't for the life of me get the top bolt off of the starter motor to inspect it, I think my engine might be dead :( my uncle said he will try plugging in his snap on one machine for any fault codes. Can anybody help please?

I think you can rule out possible engine seizure as there would've been more than just the low pressure oil warning light flashing on a few times. Also if the restricted performance light came up without any other symptoms first then that'd still provide some power.

However you say that the engine now won't turn over. So you'll have to put a spanner on the crankshaft nut and see whether you can turn it over by hand. That'd put your mind at rest on that score. Doesn't mean though that the chain tensioners haven't given up.

The starter motor not turning. And the flattening the AA person's jump battery tells me that one or more of the alternator's diodes (they change the AC generated by the alternator into 12V DC for charging) has gone short.
Or the lead/s from the alternator are intermittent. It gets very splashed and dirty down there so at risk. Only replacement of the battery with a known good -- and see whether the installed battery is taking charge -- will tell you to go toward the alternator or not.

A Snap-On fault reader might not be of much help -- you'll want someone with an iCarsoft i930 at a minimum to give you good fault diagnosis. But even then they will only be faults shown that are stored in the car's ECUs -- might not show something as electrically major as what you describe

Best I can do for now at this distance -- where are you?

Hello Firth_barge and welcome to the forum.
A pretty serious first post,wow. :shock:
I really feel for you,must be so disheartening.
I would start the diagnoses by going back to basic's and go through the process of elimination.
Have a look at the battery first,bad ones can cause all sorts of weird things.
If that checks out alright then the next thing is to take the spark plugs out and see if it will turn over by hand using the crank-shaft bolt.
If it still wont turn over then off with the cam cover's to see if anything has happened in that area.
If still no joy you might be looking at the crank-shaft being starved of oil for some reason and seized up but that is a pretty rare happening.
You'll only know that by taking the sump off and looking up from underneath and there is also another cover to remove after the oil screen pick-up has been removed.
Sorry I can't be more helpful but keep us up to date with progress if you can.
Good luck anyway,try to keep positive :) .
Andy :D
P.S Just thought you might need the workshop manual.
Here's a link to it,feel free to download it.

Good luck again.

Hi, thank you for your replies.

After getting the top end cracked open, the engine has definitely seized due to oil starvation. Lots of carbon deposit and one piston has been damaged, with no compression. Also found pieces of tensioner mixed in there which seems to me to say it is game over for this motor.

At this point, a rebuild seems impossible so my next move will be to source a replacement engine and have it fitted. I can't seem to find anyone locally to do the job. I'm at a loss right now. I love the car already and it is so clean all around so I really don't want to give up on it.

Where is "locally"?

Hi there, I thought I put that in the OP. I am based in Birkenhead, Merseyside.

Hi there, I thought I put that in the OP. I am based in Birkenhead, Merseyside.
Didn't see that for reading :oops: I ask coz there's a decent XJ8 (X308) mechanic near to Crystal Palace in southeast London that I think has a X308 3.2L in his yard that he's parting out due to chronic terminal floor rust. But that could be too far for you? You want to drop another 3.2L in? If so, then it'd have to be an '01MY or later IMO

"the X308 engine number gives easy dating information. A typical number will be 010615 02:10. This indicates an engine build date of June 15th 2001 at 2:10

01=year
06=month
15=day
02=hour
10=minute

Secondly, there are two locations where the engine number was stamped, depending on the manufacture date. 1997 thru sometime in 1999 the engine number was stamped on the block casting next to the thermostat housing. Sometime during/after 1999 it was moved to a location on the block under the left-hand exhaust manifold.
The location under the left-hand exhaust manifold is easily visible if you remove the front left-hand wheel and look through the wheel well." post from Andy (A.J.P.) August last year

Hope that helps?

You might want to try the XJ6 forum for this. Sorry, I don't know the series III so don't know what was fitted

@Firth_barge -- I thought I'd updated my post earlier, without the below my post would'nt help you avoid a pre Aug 2000 engine -- but I'll try again:
Nikasil - Cut-off date/number
The first steel-lined AJ-V8 came off the production line In the year 2000 on August 18th at 10.43am hence the engine number will read:
00 08 18 1043 or more precisely: 0008181043
With this piece of information it is simple to discern between a Nikasil and a steel-lined engine as all the numbers refer to the date of manufacture and any engine built before August 18th 2000 WILL have Nikasil bores!

Let us know how you get on?

Have you tried Bob Bate (https://www.yell.com/biz/r-g-bate-engin ... d-1167585/) as he is a Jag man and quite close to you? If he cannot help he may suggest someone who can.

I have found a 2002 engine, which I am assuming must fit, as my car has 2 cam sensors? (My car is a late 99MY)

Hi F-B,
Should be good,I take it it's a 3.2 as well.
Never had to change an engine in the X308 but the people I've spoke to in the past about it say it's a pretty straight forward procedure.
If that was me I'd check everything else is the same as well.
But I'm sure you've done that anyway.
Tensioners should be good but here's the Vin and Engine No's they start from:

"August 2001 F41863 0108130000
Start of the model year 2002 with the following changes: The timing chain guide rails
are now grey and the chain adjusters are now being made of cast aluminum and
have a plastic running surface."

If you need any manuals,PM me your email address and I'll send them to you.
Hope that helps and good luck.

Hi all, a little update, I have secured an engine, with number 010906 1422. I believe makes this a steel lined engine, possibly with metal cam chain tensioners from factory. It has been sat up for a bit so will need freeing up, but I have been assured that it will run fine once unseized.

Hoping to start the swap in the next 2 weeks so I will try to keep anyone who is interested updated, as it goes. Fingers crossed!
