I still have those 2 crisp £50 notes, if you want to admit defeat?

I managed a to find a couple of days and the first day I wasted trying to make a mount that was just too difficult to replicate so I changed my idea and went with the following :D

ImageImageImageImageImageImage

I have one little weld to dollop on that mount that I realised I missed when I was packing up :-( so I will sort that :D

Once that is all sorted then the engine is supported and all I need to do is make some bushed stabilising mounts to stop the engine swinging about too much :D

once these mounts are finished then the rest of the build should be quite easy.... Well... actually I have to cut the big bar out so that I can fit my standard massive ford inlet manifold... so that maybe an interesting challenge :D

I have also been looking at exhausts and what not and I have a fairly good idea on how I am going to run it and i think I need MX5 exhaust because of the center inlet should make my build easy :D

got a few hours in the garage today and got the engine sitton on its mounts....

The rocker box runs level and square to the top chassis rail but from one end of the sump to the other it is out about 3mm of square off the lower chassis rail... frankly it is annoying me but can't see if causing any major issues unless it wears cv joints out...

I also managed to get the sputnic mount made to fit again which is a right result :D I have two more engine mounts left to make then I can draw a line under that part and start getting the car actually driveable

Right so the out of line engine annoyed me soooo much that I decided to adjust it...

The reason why it is out of line is that when I made the mounts I used blocks of wood the same thickness as the rubber cotton reel mounts but did not account for the fact that the engine is heavy and the rubber squishes....

So, I had to move one hole 5mm and suddenly everything lines up perfect!!! Also before I moved the mount I was having to pull top of the engine over and hold the bottom of the engine to get it sitting right, where as now the engine is sitting right naturally which is perfect.

Once I moved the mount it also meant it was not sitting on the plate enough for my liking and after confirming with alan I had to modify it a bit

I decided to add a thin round bit of steel under the mount to sit on and this worked a treat... it also gave me back the 3mm compression I lost.

Once this was fitted I was happy with the way the engine sat and all is well in the world again.

I have 2 mounts left to make and so I decided to go with an easy one first.

This mount is going on the rear of the car and connects from the gearbox to the cross bar box section. I mocked it up and then got to the stage that i could really do with a poly bush in it...

I decided to try and use the mig welder to weld this up as I could not be bothered to go and get more gas for the tig so off I trotted.

Splatter is a problem but the more I use the mig teh better I get and I know the welds are strong so for now that pleases me.

I decided to have a quick tidy up and come home so I could make my first Poly bush. I got on the laser and cut 2 disks out of plastic with a the right size hole through the middle so that I could put the disk either side of the mount so I know that the center tube is central and also upright.

53013929_2503161866626302_7227027145539715072_n.jpg


I taped the first one on the bottom then mixed up the poly urethane poured it in and put the second one on the top and let it set for an hour.

after an hour I peeled off the plastic and this is what i was left with....

53145762_249577605976580_4328942123693899776_n.jpg


After the hour the Poly Urethane had cured enough but was not completely set. after 3 hours it is pretty much set and it is a tough mount for sure...

there is just enough movement to hopefully stop too many vibrations and looks like it is going to be strong enough.

I have a few more bits to weld to the mount but that should not cause too many problems :D

My next day in the garage is friday so should have that mount made and fitted then I have one more to make at the rear of the engine to stop the top of the engine moving too much so there should be another poly bush mount to make up which I am quite looking forward to

The engine is finally in and sitting where I want it...

The lat mount was a bit of a pig to do but it is in and doing what I wanted. I need to tidy it up a little but it is ok.

Once the engine was in I decided to look at the exhaust situation and I was hoping to use the original manifold but that does not fit and then so I mounted the cat which sets up the exhaust so I can see where the pipe will run under the car...

It sits nicely but need to work out how to get the exhaust passed a cross bar. I am looking at using a flexible tube but my question is do I also need to add a flexi pipe in to absorb vibration as well....

I ordered a new manifold and hopefully it fits if not it will be an expensive day.... ImageImage

Today i managed to get a few hours in the garage so I thought I would see if my new exhaust would fit.

Itsnblooming tight but it is in.

I also decided to make a start on the final engine mount which will go from the top of the gear box to the lower chassis rail near the bulkhead.

However a friend popped round to see how was doing and asked if the drive shafts line up.... Erm....

Crap

Well I have had to raise the engine 10mm a side and to be fair I needed to do that anyway ad the sump was quite exposed...

I just now need to tweak a couple of the other mounts and at last it will all be fine

As you can see from my previous posts my exhaust situation has me puzzled...

I am thinking from the underside of the engine to the chassis using something like this....

https://rover.ebay.com/rover/0/0/0?mpre ... 2161026223

That would get me exactly where I need to be and make it easier to get a silencer on....

But one question is do you reckon that this will be good enough to sustain vibration? as I do not think I can get a normal flexi pipe in between the manifold and chassis....

Well I got another day in the garage on Friday and I started off my fitting my freshly cut 5mm discs to the engine mounts to raise it my 15mm a side. I did not realise how much difference this will make but it certainly has.

I then decided it was time time to look at the inlet manifold situation and originally it was looking like I was going to have to cut the bar and move it a little. But because I have raised the engine by 15mm the inlet manifold just fitted.

Just fitting is not enough though as any engine movement would cause issues...

I was looking at cutting the bottom of the inlet off and remembered I had a spare inlet in the shed so off I went to see if i could find it and have a practice run first.

I found the manifold and noticed it had 1.8/2.0 written on the manifold and looked a bit smaller so I offered it up and it fitted great. So the next thing was to try and see what was different between the two other than the size and so I started to switch the parts over.

The air flow meter was the only thing that was not the same but I soon realised on the the manifold that came off the focus that it had a 90 degree adapter plate so once I removed that all was well with the world.

The next job is to suss out my exhaust so I think I am going to look for a round silencer and with an inlet on the ends as I think I could make that work....ImageImageImageImageImage

I have been thinking about my exhaust situation....

and I need something a little like this....

Does anybody know of anything that may be similar?

I got to the Mojo today and although I was there all day I was distracted massively by the fact teh builders had started to replace the staircase on my building... I have been waiting for nearly a year for this to happen so to say I was distracted was an understatement :D

I did however make a swaging tool and it worked good enough... I have split a few parts of the tube in the practice run but I have it sussed now...

Other than that I am a little lost as to where to go to next...

I looked at fitting an expansion tank but the one I had was too small and the one from the focus is like a swimming pool so gave up on that. I then thought I may as well start stripping out the the coolant hoses so I can get the ends swaged but even that I could not do as they are in there too well... The engine needs to come out as well first!!

so I think the next port of call is get an expansion bottle fitted and also get the exhaust sorted then I can repair the paintwork in the chassis and start putting stuff back together finally...

I also need to work out where my fuseboard is going as well....

I have not done much on the mojo really as I have been sorting the garden out and getting my bees ready for the summer :-)

I have also ran out of money so need to sell some bits before I can carry on spending:-)

Gor most things sorted now though so once I get some funds in I will be flying
