The V8 Owners Forum -

If the belt is incorrectly tensioned (slack) the alternator will protest way before the water pump i.e screaming its head off especially when a load is applied to the battery post starting or headlights heater on etc

You will breeze it your 2 years early for CAT more stringent testing

Have a look at:

May help

That guy mentioned on the link above Jools (Spitfire4v8 is the owner of the mentioned company above hence why I posted this up previously I dont recommend anyone I wouldn't use myself as I am also in the motor trade

The CUX Hotwire ecu has lots of scope TVR used them from 4.0 to 5.0 displacements (yes even the 4.6) if you need it remapping to suite I recommend http://www.kitsandclassics.co.uk/ and wont charge a kings ransom unlike some, lots of satisfied TVR owners 8) dont waste money on a generic performance c...

RR did that to allow all the casting stresses out of the block before machining

X bolting not necessary IMO unless your building a balls out screamer or aiming for big power numbers , no need to change main caps on many 3.9 int blocks they already have the full width caps fitted block and caps just needing jigging and drilling for X bolting

Spartan fan here :nw they just work and no voltage offset issues like I had with my Innovate LM2 (even grounded in the same place as MS and splitting heater and sensor grounds) :roll: lots of glitches and freezing on initial purchase of the LM2 until about 2 firmware updates in :| but as a stand alo...

Bosch 2 or 3 wire get my vote older Volvo Saab BMW GM etc , if you run a big cam ign scatter spark dialing in lots of advance etc wont be enough for warm up so some kind of ICV is essential in some instances, I agree with Dave the Hotwire stepper is a pain in the arse and often erratic in its action...

The two in trumpet base can serve purge canister and brake servo vacuum

Lucas Hotwire stock pressure is 2.5 BAR if your using just 2 BAR that may well be your misfire from an over lean AFR (dangerous for the motor)

Those bolts should be at least thread locked or preferably lock wired witnessed this problem more than I care to remember on the RV8 combination of heavy pick-up pipe and engine vibes all contributors to this issue with the result .... oil pressure woes

All that expense fuel only and no mapped ignition? missing a trick there unfortunately

You have a 50/100 mile window approx post cam break-in to load up & scuff those rings in IMO after this things are a lot slower happening

Vauxhall/GM Siemens 1588 inj's are a good alternative available newer and have a superior spray pattern to the Lucas Hotwire disc style inj's , quite a few TVR Hotwire guys use them inc myself

Sounds valve gear related at that noise frequency almost like tappet bleed down what the oil pressure like ?
