Would anyone be interested in a completely rebuilt Top Hat engine? I have two 4.6 SAI blocks that I'm considering having fitted with either Darton or LA Sleeve o-ring liners with original bore dimension.

The engine would be completely rebuilt meaning heads surfaced with entirely new valvetrain, new head gaskets, new head hardware, new tappets, new push rods, crank polished, new crank bearings, new con rod bearings, new piston rings, new cam, new cam bearings, new main seals, new oil pump, new timing gears and chain, new coolant pump, new freeze plugs, new cross bolt seals, etc.

This is how Atlantic British does their rebuilds, except without the Top Hat liners and they get $7,195 for them + they require a core or it costs an extra $1,250.

Again, just trying to get a sense for the level of interest before beginning another project.

 

According to their site the engines include "flanged sleeves".

But I am sure you can beat their price by a good margin and make a small profit.

Q&E can do the sleeve install with LA sleeve parts.

 

Ahhh yes, my bad, the minor details. More precisely -- Flanged Liners with O-Rings are not used by AB and would be installed in my rebuild. Insurance against coolant seepage into the oil pan, however unlikely that event might be. These particular liners are difficult to source but can be found with the proper diligence.

 

You can grab a rock solid RR 4.6 out of a junkyard for $1000 - Who would buy one?

 

Not you, apparently.

 

^ You're back! And spreading joy I see!

Can't wait to see what ingenius fix you come up with next, keep us posted.

 

Maybe some of those 'rock solid' junkyard engines created the slipped liner plug welding approach? Man, I wouldn't let this guy work on my Schwinn.

 

He said RR 4.6. I don't think those slip.

 

LR had a block grading system. The best blocks up until 2002 were used on the range rover 4.6 motors, after that they only made 4.6s so it was a free for all.

 

I test drove a 2001 Range Rover HSE 4.6 with 122k. The engine was smooth as silk. Meanwhile My 2003 Disco II with 85k and the slipped liner can be heard from 2 blocks away. Yeah, I would agree they graded these engines just like Intel grades its chips.
