1997' Sovereign 4.0 Starter problem, and cold start problem
Hi guys! I'm picking up my first Jag next saturday. A 1997' X300 Sovereign 4.0
The only two thing that bothers me, is that the seller told me that there is a wierd noise from the starter when first started, then it goes away. This noise occured because some road service helped him when the battery was low. they ran the starter a long while. Is this usual? And is it the starter that is worn, or the flywheel?
Also in cold start, there are some issues. If the engine is started for fae seconds, and then turned off. it will cause that the spark plugs is soaked wet of gas.
Is this common problems?

Firstly, you are NEW, so welcome to our side.
OK, different market to mine, BUT.
The starter issue may be the starter motor as you suggest. NOT a common issue, they are designed to crank an engine, but then old age creeps in now. The reduction drive section "inside" the starter is a tad weak I believe.
IF, and I mean IF, the rattle is for a few seconds after the starter has completed its task, then it will be the well documented "top timing chain tensioner unit", which is easy to replace.
Your "wet" spark plugs may the reason the starter is playing up, the long cranking that would be required to "clear" a flooded engine will certainly decrease the life of any starter. Lots of reasons for that, and a few below for when you get it home.
1) Cam angle sensor is mistimed (thats the wizzy thing where a distributor once lived).
2) Spark plugs are old, or wrong heat range, or wrongly gapped.
3) FPR (fuel pressure regulator) is having a hissy moment.
There are more, but lets not scare the hell out of you just yet.
Having said ALL that, I NEVER, and I mean NEVER start a Jag engine and shut it down before it has got some heat into it (about 1-2 minutes). This I learned the hard way with my many V12's. If you cold start them and shut them down within 2 minutes, the chances of a "clean" restart are slim. My mighty 3.2 X300 is the same, if I start it to move it to get the other Jag out, and shut it down, the next start is always roughish, until it clears that bit of excess fuel. Wet spark plugs, NO.
