sorry, dont mean to hi-jack the thread or anything but i dont wanna start another identical one. i have a 99 and just like my 00 i smell gas in the oil and it burns a lot of it, also, i pulled out the front driver sparkplug and had oil on the threads. i think my rings, and maybe something else is shot. is there a kit for a 4.6 rebuild? the longblock seems a little pricey.
 
Trust me, you wanna go with a new shortblock - no longblock necessary. Think about it...your gonna have to yank the engine, tear it apart, replace the rings, and put it all back together. Unless you plan on doing this yourself, it's gonna cost you a lot of money - and a considerable amount of time if your not familiar with doing this - it's a lot easier to go with a nice forged shortblock, especially for future mods. MMR offers a 1 year warranty on their blocks for workmanship defects. That's where I ended up getting my 5.0 stroker from.
 
If you are mechanically inclined I would and did do it myself. I saved about 1800 doing myself as opposed to paying a builder to do it.

It isn't for everyone but if you are able then do it. You might learn something too.
 
There was a really good article in MMFF a while back, I think it was called
redneck rebuild, where they did a rebuild/refreash job on a 4.6.
The whole point was to see how cheap they could do a quality rebuild.
If I was home I could tell you which issue it was.
 
I was thinking of doing an engine rebuild/upgrade because I want to run more boost than I am now. So I figured on having to get a new forged crank, rods, pistons, and all supporting parts. I looked at the modular mustang racing website and was pretty shocked how the built shortblock costs about the same as all the individual parts. Plus you have the piece of mind that it was built correctly. I'm thinking of eventually just getting the whole new engine, and saving my stock one for a Cobra kit car... Always dreaming...

but what about the heads, timing chains and guides and all the other stuff that doesn't get replaced with a new short block?

IMHO unless you had some sort of mechanical failure in the bottom end of a low mileage motor it makes NO SENSE to just do a short block, you'll just end up having to do a bunch of labor twice (or more)...

If there's nothing wrong with the heads, timing chains, guides, etc....whats the purpose of replacing them unless he wants to build up the engine? Just transfer them to the new block.
 
it's a 10 year old car with a worn out ring, what are the odds than nothing else is worn out or won't be needing attention in the next year or two?

I say do it once and be done with it :thumbs:

I agree with getting everything done at once, but the financial aspect does weigh in on these type of situations as well; not everyone can go out and drop another 2K on valve train when there is no indication anything is wrong with the current setup.
 
Here is my suggestion after a few rebuilds. Buy a rebuilt long or shot block from a reputable manufacturer that has experience like D.S.S., Livernois, or any of the reputable dealers. Be real careful letting general machine shops that are local do it. 3 rebuilds later, I learned my lesson the hardway. If you aren't going to run more than 400hp, buy a used 4.6 long block with less than 30K. There are a lot of them around.

I agree, let the pros handle it. Rebuilding it yourself or letting a random mechanic do the job leaves room for error. Last thing you want to do is rebuild the engine, have it pop, and do the job twice. Save yourself the effort and pay a little more to have a reputable company build the engine.
 
Their are 2000+ engine that sell on ebay for 1k with 70k+ miles. Can it fix my 98gt ? my tranny is grind in reverd , but if I put in 4 then rever it will not grind, should I replace the tranny too ? and my clutch is vibrate, its good ideal to to king cobra at the same time ? thanks
