Moogs Motahs - sinking the seat


The Moog

Recommended Posts

Got the camshaft housing back this morning.

 

They had welded it up all the way around.

Now in theory I should take it somewhere to get machined. Instead I channeled my inner Dave and got the Dremel out.

 

I mainly used the sanding wheels to start taking it back on the key faces. It was slow work but quite satisfying.

Many were used

Then out with the wet and dry

Used the old camshaft and oil seals to test fitbce2f817295268e3c6967daadfcc9015.jpg91234b617f6ba8effe3db7fbf36b8923.jpgd0d86fc05bd2bb03f1fae74f2e855e60.jpg89801e1a101f623221a4dd6657820daa.jpgd34d35260d209dee0b5a9ca5e26c7919.jpg

 

Seems to run smoothly and no rough edges. I think I should get away with it.

 

 

Missus Moog is at work so used my parts* washer

Embolden by that sort of success I cracked on with the other bits

 

First up was that stupid tensioner bolt. I applied many heats, hammered in the next size up allen and lo it workedaed51c60084435e10af8ac34abe2ca11.jpg

 

Boom. Very happy bunny

 

Hbol said that there are three bolts and the bottom of the timing cover falls off. After spending 20mins trying this approach I ended up whipping off the crank pulley. 8e02ba52f013e5a4abd199c42e73f36d.jpg

 

As you can see there isn't a bottom bit that comes off. 5dec1378c472d957c41ad06c607f5bca.jpg

 

That gave me access to water pump

Shhh don't wake the boss

Probably a good idea that the water pump was changed

Shiny new one back on

Phone then died so no more photos.

 

Timing bottom cover back on and got the head out of the dishwasher.

 

Next jobs are to time up the crank and lock it. Then get the camshafts back in. Then fit new timing belt, tensioner, covers, aux belt, coolant then good to go.

 

Couple of questions for the masses

 

1) I have broken part of the timing cover - any easy way to fix these? Does plastic welding work or plastic staples?

 

2) Tensioner bolt will need to be replaced. Are these anything special?

"plastic welding" works usually but needs clean plastic. It's basically just melting a thermoplastic with a soldering iron and knitting the two bits together.

 

If it's a flat piece, and there's a few mm of clearance behind, then drill some holes either side the crack and thread tie wraps through like the Drift Krew do with their bumpers, yo.

Moog - I use one of those small gas torches for baking...... creme brûlée torch thing. It's so far melted together bits of the car, engine cover, undertray bits, plastic mounting for rear bumper and the crappy garden table the landlady left here...... all still in one piece and with a small flame it was easily controllable. 

If it doesn't work out you can surprise the missus with a nice pudding!

It was very nice to meet you Mr. Moog. It was a day of many firsts. First convertible driven, first mid engined car driven, first MG. Mr. Moog also very kindly let me drive his MX-5 and Pug 406. Another two cars I had never driven! Overall a very good morning's skirmish and the MG very happily barreled along the motorway 94 miles home. It uses remarkably little fuel and looks really rather smart. Thanks again!!

Timed engine up and locked the crank

New head bolts came and were fitted properly e0eb7d42e5e9edaf7b28ec5af1ba4506.jpg

 

Head cleaned and ready

So hbol says

 

set camshaft at 8pm on exhaust cam - tick

 

Add thread lock to patch bolts - tick

 

Tighten bolts diagonally carefully - tick

 

Use a torque wrench set to 25nm as max -tick

 

Crack the camshaft holder in a different place - tick

Ah bugger, still had my t-series head on. Its a development of the m-series but probably won't fit sorry

Camshaft housings look the same. Going to lob an offer on it.

 

I think this has to be a labour of love to get the car back on the road.

 

Will get a grown up to help me fit it as well.

It’s moments like these that just make you go “why didn’t I give this to a fucking mechanic?!”.

 

I’ve had similar fun* installing rear shocks on my old Sonata, I ended up breaking everything I touched. Such a ball ache and it’s the main reason I have not got its current faults repaired.

 

But, with a fair amount of blood, sweat and tears, anything’s possible (as long as you can afford it!).

Wtf is going on here? I don't get why these are cracking. Is the surface they sit on not flat or something?

Someone on rover800 forum suggested that - whether the head is fucked. It was put into garage as it was leaking oil and they thought it might be HGF.

 

When we got it running it wasnt leaking oil so assumed that was wrong. Had a head gasket and skim _4k ago but 10 years ago. Not sure they put anti freeze in based on water pump

To be honest I didn't check the head, I assumed it was ok. Will have a look later.

 

I checked the size of the camshaft just in case

 

Old

New

Some more pictures from it - you can still see the gap. 75b5c61beda00ececf8912e6e70b1700.jpg5754a6ba63069069d2e3419c299cda40.jpg

 

it has cracked pretty comprehensively

And my cheap crocs have got a hole, I found out by stepping in a puddle.

Will roll the dice with a head but after that I think it is call it a day

 

AHH well beats losing it in the bookies.
