John Eales crank damper, oil seal journal eccentricity
Hi all, I am building a 5L Wildcat engine for my Chimaera. I was having problems with valve gear and springs. Got that sorted now. Just one problem after another with this build though, which I expect, but some are problems that should not occur. Long version -- I bought a performance crank damper f...

Re: Rover V8 Wildcat heads, valve gear problem
Hi, Thanks for the reply. Lloyds did supply the pushrods, but not the followers and cam. I did get the binding issue resolved by using 5/16ths rods and adjustable guide plates. I had to modify the guide plates slightly to allow for sufficient adjustment to get the correct pushrod centre-to-centre di...

Re: Rover V8 serp oil pump relief valve
I ordered a 300TDI one from Ebay. It does indeed look the same. But it's twice the size
I tickled the old one with some Autosol, and there wasn't a mark on it, so I re used it.

Rover V8 Wildcat heads, valve gear problem
Hi, I am doing a trial build of my 5L engine with Wildcat heads from Lloyds and Kent M238 cam. With the pushrods Lloyds supplied (3/8ths, 8.8" long) my valve gear binds up. The pushrod binds up against the rocker body, and the pushrod looks to just graze the pushrod hole. With the lift of the M...

Rover V8 serp oil pump relief valve
Hi all, I want to replace the oil pressure relief valve for my 5L build. I have the interim Serp cover with Dizzy. The plunger/piston and spring don't look like they are available anywhere. I have read that they never were. All you could get was an entire new front cover, apparently? I reckon I can ...

Re: Piston- Deck clearance
you do not measure by rocking the piston. you measure at the centre of the piston where rock does not affect it. And rock is a different thing altogether, affected by piston to wall clearance, heat, etc etc when running. I can't, not straightforwardly, because my valve cutouts are over the centre l...

Re: Piston- Deck clearance
So I checked for deck flatness, and I am happy they are flat. They should be because V8 Dev skimmed them when they did the top hats. I haven't attempted to switch any pistons over today, but I did devise a way to measure my deck heights, using a straight edge overhanging the deck, measuring the diam...

Re: Piston- Deck clearance
Hi, Thanks for the replies. I'll try and get a picture. Yes, it occurred to me after my last reply that you meant to just switch the whole rod and piston assemblies to eliminate possibility of stacked tolerances in the rod and piston. Doesn't matter for now if they are not in their correct holes. Ye...

Re: Piston- Deck clearance
It took some practise to get consistent measurements, but I am fairly confident in them now. I checked them several times. I can't measure at the wrist pin due to valve cutouts and piston dishes, so I am measuring at the inner most edge of the piston, with a DTI and rocking to get two measurements, ...

Piston- Deck clearance
I am just doing a trial build of my 5L Rover engine. Boost Performance crank, machined to 86.36mm stroke, 6 inch Chevy rods and Icon pistons, 1.25 inch compression height. 96mm top hatted block by V8 Dev I have just been measuring my deck clearances, and got some weird results. Don't think they are ...

Clutch options TVR Chimaera, 5L Wildcat. Also, gearbox
Hi, I am looking at clutch options for my 5L Chimaera Wildcat project. I am using M238 cam, and hoping for 400ish horseys. My car has the T5 box. I was going to go for the Mcleod 10.5 inch single plate that V8 Tuning stocks, but it is only rated to 350hp. I thought maybe I should go for the dual pla...

Re: Rover main bearings big journal
Hi, thanks for your reply. Ah, ok. I already ordered Clevite P series for the rods and King AM for mains. Looks like I didn't make the right choice from your advice, certainly for mains. I nearly ordered genuine LR ones, but I assumed they would be aluminium too. I am only at the trial build stage, ...

Rover main bearings big journal
Hi all, I am about to start putting together my 5L stoker motor, using Icon pistons, H beam rods and Boost Performance crankshaft that I had machined to take Chevy rods. Using Wildcat heads also, and Kent M238 cam. Was hoping to get some bearings ordered this week to do a trial build at the weekend ...

5 litre Wildcat stroker motor advice
Hi all, Years since I posted on here. Looking for advice on my current build. I have an interim 3.9 block that has the full width caps. I have had the cross bolt holes drilled and taped. I intend to have the block top hat linered by V8 dev and bored to 96mm. I have a pair of Wildcat heads, together ...

Re: Whining alternator problem
The pump is behind the back wheel, but it is definitely the alternator whining. Another suspected culprit is my starter motor, if that has a short in it maybe that is causing a massive load on the alternator? The starter is only 6 weeks old though. I find it very suspicious that the noise goes away ...
