oil spray
Avos,
Thank you for your reply. but i have a few more questions.
I am about to start my engine rebuild and would really like to implement this if possible. I have gotten the 4.0 engine rebuild manual from the Jag GTR at http://topix.jaguar.jlrext.com
This file gives any thing and every thing some one would need to know about how the 4.0 is built.
As i do not have a 4.2 engine laying around to examine, and i do not have the rebuild manual for the 4.2. i am some what at a loss for some of what you said, as i dont have a full understanding how the 4.2 sprayer system works. can you elaborate a bit for me?
I assumed the oil pump system would have to be updated to the 4.2 system. Higher flow/volume
And another random question, can the 4.2 forged crank be put in a 4.0? i am thinking its a maybe as the piston bore is the biggest difference as far as i can tell without solid documentation.
Thank your for your help sir. I appreciate it a grate deal.

Maybe now is also the time to reconsider to use a 4.2 block straight away, you can still get these relativly cheap and with low milages. It depends a bit on your plans though.
I can send you a picture this weekend showing the oil jets.
The 4.2 crank is stroked compared to the 4.0, and iirc the big ends are smaller in diameter, so you can't just swap it.

You can stroke the 4.0 to a 4.2, you will need the crank and conrods to do it......I know this as I have done it, the bores are identicle so no problem there.
I have rebuilt my XKR into a 4.2 and it is a nikasil engine, this is how I know about the oil pump as I have one of those too but decided this was too much hassle and kept the standard 4.0 pump

crank/rods
Thank you guys,
In my case, getting ahold of a good quality used engine in the states can be problematic..
and a new crank and con-rod setup for a 4.2 to stroke my 4.0 will run over $2K us.
Now to my understanding, the oil sprayer's are part of the connecting rod? or are they a block spray nozzel setup that i have read about used on some bmw engines,
thanks

Avos,
Thank you for the picture. That helps allot... I have now made up my mind i am going to do this.
do you by any chance have the part# for the sprayers and the bolt?
Also, can the 4th bolt on the oil pump be drilled and taped? or is that not feasible?
And i have to say, i love what you have done with that block. its a nice bit of modern automotive art now! LOL and i mean that with the utmost respect.
