A shroud will certainly make any fan more efficient.  I was simply suggesting a simple, inexpensive, bolt-on, and fairly significant improvement over the stock four blade metal fan. I am somewhat amused at the discussion of maximum efficiency with shrouding, and eliminating power drain by going electric; gentlemen, this IS a tractor motor we ...

You may want to consider using the stock 8-blade plastic fan from the TR-6. It is lighter, moves more air and is undoubtedly better balanced than the original four blade fans.  The part should be easily attainable through Moss or any number of other vendors; I purchased one as recently as this past spring for a TR-4A restoration. Its a straight ...

Peter, You were spot on regarding the linkage to the PCV valve.  Sealed the pushrod tubes externally with a light application of JB Weld.  Checked the PCV and it appears to be incomplete and cannibalized. Internally the valve has a set of four prongs that appear to guide a small pin which rests on the one way valve in the lower portion of the ...

After spending five years restoring a 1966 solid axle TR4A which sat for 20 years, it is on the road.  However, it is a short road!  After slowly bringing the motor back to life, it appears to have good compression and oil pressure.  The big problem is oil leaking from the cylinder head.  I have isolated it to where the pushrod tubes go into the ...

After much study, I believe I figured it out.  Based on the configuration of the bracket I believe it bolts to the forward body mount just to the right side of the RH radiator mount.  The mount is a threaded rod which can be adjusted for length and appears to be the proper location.

In the four years since tearing down the car, I have forgotten where the radiator overflow bottle bracket mounts.  Either the body man inadvertently covered the mounting hole or I am having a senior moment...  In either case is there someone out there who can tell me specifically what the bracket mounts to or better yet supply a ...

A possible fix which may save you a world of aggravation.  I had the same issue with the hood on my TR4A: no sign of holes drilled for the lettering. I mirrored the pattern which is on the trunk lid, and drilled the holes but it was a nightmare.  Despite having a good template, a minute variance when drilling will result in crooked ...
