    Hi Steve, Thanks for detailed answer, text and photos did help me understand issue a bit better. What I shall do, if you dont midd, is to go straight forward and ask Jaguar engineers directly about this issue and show them how you delt with it on your car. Perhaps they will be able to provide...

    Hi SID447, I agree with you in regard with fuel injectors. Yes, S Type R comes with forged pistons - I have heard that from jaguar engine engineers, I am in contact with one of them via e-mail. They were preparing a solution - proposal to me, but they were a bit slow, in two weeks I havent...

    What shall I say, lucky you - you are right - it is a last cyilinder in the row just in front of a driver, on the left if you are looking from the driver seat forward. I was warned by few experienced mechanics that it was most probably the case with both of my engines - now I am paying attention...

    Forged pistons for 2002 Jaguar S Type R 4,2 V8 s/c

    Hi Sid447, The scratch was inspected by 2 mechanics and they claime it can not be polished, it has to be rebored to stage 1. But as I was told then I need 1st stage pistons - and nobody has the idea where to find them. Mahle pistons are OE, but they sell it through Jag dealers only, and the...

    Forged pistons for 2002 Jaguar S Type R 4,2 V8 s/c

    Did all that. I have sent out some 20 e-mails to different piston manufacturers or resellers - Pistons online, AJ pistons, and others I dont even remember now. Mahle did reply twice to my e-mail and have promised to see if they can help me. Main problem is that one cylinder is scratched and I...

    Hi Sid447, Thank you for your post. I have contacted Mahle about a month ago - I gave them all the details they have asked for - and then silence. No answer whatsoever...

    Forged pistons for 2002 Jaguar S Type R 4,2 V8 s/c

    Well I give up. I just bought new rebuild engine. What I have learned is that pistons are Mahle OE, but you can order them only through Jaguar, and Jaguar takes abbout the century to reach decision and offer them for sale. I tried Jaguar service here in Zagreb, Jaguar tech. department in England...

    Forged pistons for 2002 Jaguar S Type R 4,2 V8 s/c

    Bad news. One cylinder got schratched and according to my mechanic it has to be bored on 1st stage. Problem is i am not sure it can be done here - perhaps but then I need piston kit custom made. Tomorrow I shall see my mechanic for more detailed info.

    Forged pistons for 2002 Jaguar S Type R 4,2 V8 s/c

    Problem is Ford shall reply and forward me to the Jaguar, and they shall offer regular piston kit. I think that this current engine is Cosworth engine (or I am wrong) Jaguar both in 60ies and race with it for some time in Le Mans and F1. This is a civil version of that engine, that have been...

    Forged pistons for 2002 Jaguar S Type R 4,2 V8 s/c

    Well I have that idea as well on my mind, but trouble is to have it done by reliable person or company. Idea with piston is, since I did some tuning on my car in the past, I am thinking of using this situation and improve the engine a bit. It is about forged, light weight optimized aluminum or...

    I am sorry to hear that you also have the same or similar problems. As for the car - I had so many problems with it that it is impossible to cover them all - first I believed its the low quality, but it is not. The service is my main problem. Trouble is, if I fix it somewhere else I loose...

    Forged pistons for 2002 Jaguar S Type R 4,2 V8 s/c

    I do agree with you. It took me 6 years to find one near me. The closest best solution so far for me was Munich, Germany - Auto Koenig. This new mechanic in Zagreb used to work for Jaguar then he has opened garage of his own - so far I am satisfied. Jaguar is rather new car on Croatian market...

    Thank you for your post. I have I believe contacted all or the above mentioned companies via e-mail and I am still waiting for reply. This morning I have received a reply from Racing greens cars that they do not have forged light weight piston kit and that they do not know if anybody is...

    My main problem is official Jaguar service in Zagreb - they charge a lot and provide in return nothing. I took my car in Germany, Munich a year ago in Auto Koenig and everything was fine untill cooling system pipe started to leak. Official Jaguar service did not have the replacement so they have...
