rebuilt engine

I am very close to hitting the buy it now button on this engine but first wanted to ask if anyone has anything bad to say about this company.Are these motors junk with knurled valve guides?Are they worth the money?

Should I look elsewhere?

Re: rebuilt engine

I have never seen a rebuilt crate motor that did not have knurled guides. Personally, if you can stand the wait, I would have a local machine shop rebuild it for you. Around here you can get it done just as cheap or cheaper. It just means waiting about a week, but you know what you are getting. Also most machine shops warranty their work, not that the crate isn't, but if you have a problem, it is nice to have the people you are dealing with, be local

It is so nice to see someone thinking about the valve guide knurling. It just about guarantees that the engine will be burning a lot of oil in 10K-15K miles. They just bet you either lose the paperwork or sell the vehicle.

Re: rebuilt engine

Yea I want to avoid knurled guides at all cost!

I talked to my local napa machine shop today and they gave me a price of about $800.00 just for the machine work on the block and head and assembly of the head.That seems steep?The rebuild kit(dana)was like $650.00 more.....so I would have about 1500.00 in a motor that I would still have to assemble my self.

Are they trying to bend me over on this???

Re: rebuilt engine

I put a Jasper in my Y2K XJ. 3/75 warr. parts and labor. You put the first one in and if it fails take the Jeep to a Jasper dealer and they will pay them to put in the next. Pretty good deal at $1750.

Re: rebuilt engine

for those of you like me who hadn't heard or knurled valve guides:

From the Web -
The engines covered in this guide use integral valve guides. That is, they are a part of the cylinder head and cannot be replaced. The guides can, however, be reamed oversize if they are found to be worn past an acceptable limit. Occasionally, a valve guide bore will be oversize as manufactured. These are marked on the inboard side of the cylinder heads on the machined surface just above the intake manifold.

If the guides must be reamed (this service is available at most machine shops), then valves with oversize stems must be fitted. Valves are usually available in 0.001 in. (0.025mm), 0.003 in. (0.076mm), and 0.005 in. (0.12mm) stem oversizes. Valve guides which are not excessively worn or distorted may, in some cases, be knurled rather than reamed. Knurling is a process in which the metal on the valve guide bore is displaced and raised, thereby reducing clearance. Knurling also provides excellent oil control. The option of knurling rather than reaming valve guides should be discussed with a reputable machinist or engine specialist.
