I have a 2004 S type R with a blown engine. I am considring rebuilding the engine myself but cannot find reliable Manual to do the job. Is this advisable or should I be looking Looking to replace with a low mileage used, new or re-manufactured. Any Info or expreinces you can share will be appreciated.

thanks in advance

I'd strongly advize ya replacing with a Jaguar remanufactured engine. You'll dump more money in a "do it yer selfer" as opposed to a fresh, correctly assembled Jaguar reman. A member here blew his too and paid $4500 or $4900 for a Jaguar remanufactured long or short block? Check it out. If ya have a problem finding a retailer, contact me and I'll have the member contact you with procurement information.

 

I would assume it really all depends on why it is blown. That would determine if its worth doing all that work and spending the money. I would go with whats gonna work with your budget and time. If you got a blown rod and it punched through your block you might be better off just getting a used one. Do you happen to know what exactly happend to it that might help people guage what would be a better option for you??

 

JPNJAG, Vance makes a lot of sense in specing the cause and location of engine failure. I sent a private message to the member who's motor blew and swapped in a remanufactured motor. I'm pretty sure it was $4500 for a Jaguar remanufactured short block (minus heads). I or he will contact you soon.

 

JPNJAG, Check: jaguarpartscenter.com First you'll send in your blown motor as a core ($240 shipping). You send them $4800 and they'll send you a fresh reman. long block. If you don't send your motor first there is a $2100 core charge that'll come off the total when they recieve your motor after the new one is in. So it makes fiscal sense to send your motor to them first. All you do is pop on your intake and exhaust. This is the best price you'll find. Comes with a warranty too. The member who blew his engine and went reman. passed this info to me for you. He said the cost of all the internal parts including gaskets, head bolts, bearings, pistons, rods, etc. will cost ya ton! And if not assembled to the "T" will cost ya ton more. Go for it. You'll have an 04 STR with 0 miles on the motor. I'm already jealous.

 

Do they specify what's replaced in the remanufactured long or short block? If it doesn't come with the heads that's not such a good deal.
If it's everything and all the parts are new go for it. You can't do it yourself for that kind of money.

@Jpnjag,
What was the cause of your blown engine?

I know you may not be charmed by a used engine, but am sure you can find a relativly cheap low mileage block secondhand. And you then can still sell of the good parts from your block.

 

Bob, the jaguarparts.com reman engine is a "long block" assembly= block + heads. It's remanufactured with new bearings, sleeves, seals, gaskets, etc. $4800 is not a bad price to pay for a fully reman long block engine. Avos makes a point in that a low mileage "salvage" engine can be procured, but a low mileage specimen will cost just a little less than a "0" mile reman. long block. I'd go with a reman long block for $4800.

 

You can also try www.car-parts.com I did a quick California search and came up with a few used motors under $3,000.00

 

qualityusedengines.com has a salvaged 04 STR long block (block and heads) with only 36k on the clock, with"carfax", $4500 w/free shipping. Or ya can check out Joycesjag's salvage finds for $3000 and under. Ya want a low mileage "carfax" long block motor. Or ya can go with a fully remanufactured long block for $4800 (0 miles)?

 

So the heads have been rebuilt?
What about pistons?
If they rebuild a motor with high mileage you might want new con rods too. Lot's of stuff to check.

It's usually not the same as a NEW motor unless you really know the donor engine (no one does) and unless the rebuilder is meticulous.
They just have to make it to the end of the warranty.

Maybe it's all of those things. You need to check.

I was born a skeptic. I asked my mother for id at birth ...

You id'ed yer mom at birth? LOL! Yer a card Bob. Yes, the reman. engine has rebuilt heads and block.

 

"Jaguar workshop manual" (ebay $10).

 

Thank you all for your valuable advise. I am conatcing the recommdned sites and have started gathering the necessary infmation.

As to the reason for the blown engine, It ran with no oil for some time (Oil check lite came on after only two quarts of oil was remaining in the pan). This was a result of allowing my Daughter to drive the car for some time (I know That was a stupid thing to do, but never again).

After the lite came on, and noticing a faint knocking noise, I put 6 quarts of oil in it and continued driving it for a couple of days. After the two days we noticed a loud knockng noise when the engine is started. I took it to my Mechanic and he siad I need to repalce the engine. It still runs with the loud noise, but the car is garaged and not being used. I can only guess that the head needs new valves at a minimum not to mention what ever else has gone bad in the block.

 

ok here's my route - there's things your man can check before you go for a replacement. (to me, a replacement is the cop out option)

seeing as the engine will be coming out....
*A compression test on each cylinder with confirm if valve seats are intact.

*Check the crankshaft main bearings. Luck plays a big part. Your engine might be salvaged. Dropping the sump pan/bed plate he can assess the state of crank and bearings. Bearings can be bought easily oversized if crank needs machining.

Removal of timing cover and replace oil pump.

A blown engine to me is a piston connecting rod poking out the side of the engine block, not oil starvation damage. I've seen many engines brought back from this state with a bit of deft spanner/machining work that shouldn't cost telephone numbers.
I see you're in California, this is probably the mecca for auto engineering. The last resort is a new/recon/low miles etc unit.

If your man doesn't fancy the work, he's not worth your money in my opinion, I'd ring round Jaguar specialists that can and do bottom end rebuilds, and get a price.

 

Yep, bearings are burnt/worn. Slap in a remanufactured long block or procure a low mileage salvage engine. Sorry this happened. It's characteristic of the STR to consume a quart or two in three thousand miles or so.

 

I believe I read the Jags crank can't be rebuilt. If it's turned there's no oversize bearings to fit it. If you're into a bottom end rebuild you may need a new crank?

 

Wrong, reading vs doing?

Jeez Sean...for my 2 cents do I at least get a "I tried to help JPNJAG" tee shirt? I wrote I wasn't sure if the stock crank could be rebuilt, not: "I'm positive....". However, I did read that some Jag cranks are either not rebuildable and/or not worth the cost vs a new or salvaged crank. I dropped a low mileage salvage motor in my ex 02 X-Type 3.0. The cost and time of a bottom end rebuild outpaced that of just popping in a salvage motor.Though it's noble of you to encourage JPNJAG to go the do-it-yer-selfer route, again the time and expense of this endeavour on an STR may cost him both a lot more time and money, as opposed to just dropping in a low mileage salvage motor or a reman long block. Aside from yanking the motor, his mechanic may charge him for its disassembly in finding failure points and there's definitely a charge for its re-assembly. Who knows if after re-assembly something else was wrong or goes wrong? A reman or salvage motor comes screwed (proved) together. Perhaps in the final analysis JPNJAG will choose to learn how to conquer a rebuild with his own two hands? Otherwise I feel yer doing a damn good job providing both encouragement and technical detail.

 

jpnjag since you are considering rebuilding the engine yourself, you would need to do your homework and price out all the parts needed. I read sometime ago another member in the "X Type" forum rebuilt his entire motor after basically a melt down and he had spent twice as much if he went the manu. motor or a salvage. He did state he had "fun" doing it but not worth the ching. Just something to consider.
