I thought cam belts were like condoms .....

What - you mean you can turn them inside out and use them again?

Not sure I'd have a use for them if that's the case. 🤣

In a way condoms and timing belts share a lot in common... If they break during operation... You are f**ked !!!!!!!!!! Hahahahahaha

[andyblackman777]

Also condoms are inexpensive as opposed to having a baby!

Put new belts on. Please.

Yes, this is true !! We replaced belts 9 months ago and since have done less than 1000 miles.

I asked him if we should replace belts (from my knowledge it is not good to stretch and reuse belts) but he said they are brand new and fine to use !!

God help me !!! LOL (Please be gentle with your responses !! Haha)

Would you ever consider reusing engine oil?

Or course not !!

For Makis, this is what we talked about.

Interesting screen shot, v8GTmac1, are we looking at tuning the Megasquirt for some VF turbos?

Ha you see that.  I was looking for an upgrade on the subby powered factory Five 818. 

 But Speaking of the Lotus and megasquirt If only I had one extra output to control the boost solenoid.  Not such a bad thing that I’ve run out ?

[snowrx]

Well, the MS3X has outputs galore, and lots of boost control options. I'm still waiting for something terminal to happen to my WRX so it can become an 818. Caught a deer this summer, but damage was limited to hood,headlights and grille so Factory Five missed an order.

Small progress on my car... Early next week the engine should be back on the car...

Interesting BOVs

looks like there was room to attach to the hoses. 

[MD355]

I have no idea if these BOVs are correct !!

I found them from the previous owner...

They do have an interesting effect on the car though..

Because BOVs open and release the compressed air to the atmosphere when the throttle body is closed (gas pedal released), when I let the gas go at high rpm and slam on the gas again, I get fireworks at the back... It must be excess gasoline without enough air (as it is released from the BOVs) !!! Lools and sounds VERY COOL !! Check out the video below that I filmed last winter...

Hi Makis,

If you have the option I would recommend having those heat shields replaced with ones made from thicker stainless. They are prone to cracking and the buzzing noise that follows is very very annoying and really difficult to fix with the engine in place.

The other task you might want to consider while the engine is out are the radius arm bushes (#42 and surrounding bits in the diagram) and check the status of the water pipes that go through the chassis as these can only be changed while the engine is out. I know the list of jobs you could tackle is endless (check the state of the fuel tanks) but if they are close to needing replacement you would be annoyed if no one pointed this out before the engine goes back in. 👍

cheers

look at this port on the head. It’s is 1/4-18

if you can order a fitting to reduce to 1/8” npt. You can hook up a mechanical gauge and monitor true oil pressure on first start.

Some and most gauges already come with 1/4” adapter strait to the head. 

[ramjet]

I am going to go out on a limb here and suggest that I would be doing nothing, performance wise, other than the standard tune that Lotus built these cars with.

There have been enough comments on here about build points, from your images, that look like the build procedures from Lotus themselves have not been used.

I would not subject your new engine to anything other than the Lotus setup until the engine has been proven or you just may end up with it coming out again far quicker than what it has taken to get to this point.

I hope that nothing happens and everything goes great.

Up to you.

Don’t forget to fit the cambelts...

[MD355]

I thought timing belts were optional on the Esprit !!! LOL Hahaha

[Barrykearley]

Most V8s don’t need them really anyway as they normally sit decorating garages

Rubbish

URGENT HELP NEED :

Good morning my friends !!

Today my mechanic called me about a problem he experienced.

As he was about to put the timing belts on the engine (with the marks he had made before he disassembled the engine) he realized that as he rotated the engine after 5 rotations the bolt that holds the pulleys of the timing belts would come loose and the timing belts would stop moving !!!

He applied the correct torque to that bolt (see picture) but still even the slightest resistance from the compression of the engine would make this nut come loose...

He removed the spark plugs (no resistance anymore from compression) and the engine and timing belts rotated normally... So there is no obstruction to the piston movement...

So my question is : What are we doing wrong about this nut that holds the two pulleys of the timing belts (please see pictures) ?

Now my mechanic had to remove the valve covers, so he decided to time the engine as the factory recommended... What page on Workshop Manual is the timing process of the factory ?

All responses and help are welcome, but I would appreciate if you don't attack me or my mechanic for making any mistakes !! Many thanks in advance !!!

My jaw is open..... 

Are you sure that the correct IMS bolt has been used? It could be that the thread is bottoming before reaching sufficient clamp.  I'm assuming that the flywheel is locked while torqueing the bolt. 

I would also recommend to fit a Scotch Key on the IMS and primary drive pulleys to ensure that they cannot drift even without 100% clamp.

There is a great and simply tool developed by Gonzalo Mendoza for drilling the IMS and pulley's in-situ.   I have one you can borrow if you like.

Your builder needs to be very careful not to force any apparent interference, while he re-establishes the correct crank/cam timing.
