Motivation is high, work commences.

Replaced the drum brake shoes. After doing the ones on the Hiace, these were easy. Not sure if it just because of the design or Im getting better at this stuff :p
Did not end up replacing the slave cylinders at this stage. 3 of 4 pistons move nicely, one has a small sticky spot. Brake pedal much firmer! Bearings sound good still.

I want to get an adjustable pan-hard rod so I can re-center the car after replacing the rear springs and shocks.
Trailing arm bushes look like a PITA job, might need a press?! Then again, they might just fall out!

Temporarily fixed passenger door window that was falling out of its guide and getting stuck, found the bottom of window guide all rusted through too.

Off to BNT for some more parts tomorrow, my favorite place, especially after getting some sweet discount on some Jonesway tools that were on special for less than half price. New 1/4" socket set and 1/2" impact driver set made their way home with me. (I did actually need these...)

Is there a sway bar inside the axle beam? Looks a little like the late model setup.

Replaced the rear gear box mount also. The original one had broken, not sure how long it had been that way. I cannot wait to take it for a spin with all these new poly bushes!

While awaiting a replacement radiator, there is only so much I can do at this time so I decided to complete a "small" job, replace the steering wheel. Also got out the Armorall and threw some around the interior.

Current "big" jobs that I have parts for:

Reverse intake manifold
BD10 cams and gears to fit

Might do the cams next as I do not have anything else worked out for the intake manifold replacement job yet.
Any tips and tricks for cam replacement guys?

New Years Day - do something for you that you are interested in.

Replace Camshafts

As you know, this can be a big job for the amateur backyard mechanic so I was a little apprehensive about undertaking a job like this for the first time, but confident.

Located hydraulic lifter that had faulty one way valve and ticked when engine was running. I could not take it apart to free it, tried soaking in degreaser and pumping it, no joy so will need to get a new one.

All was going well, got the old camshafts out (hollow GTi ones) and started assembly of the new BD10 shafts that I purchased some time ago, apparently only had dyno use.


Exhaust cam done

A section of the wall had broken off and was lying in the packaging. Damaged while in use, in transit? Who knows.

Brain says - you can still use it, they don't spin that fast so centripetal forces, balance etc will be fine.
Gut just says no.
Brain says - cannot afford a replacement yet so just use it.
Gut says, I agree but still don't use it.

Michael....that’s really disappointing. Sorry this happened to you.
My take on it. Firstly it won’t cause the camshaft to crack...it might affect balance but like you say it’s half crank speed....personally being so close to the centre it shouldnt be a problem. It’s a thrust face so lightly radiusing the cracked parts so no picking up on the Ali cap should solve that.
Camshaft won’t be bent...they are either straight or cracked in half. Any other damage?

I’d dress the edges and use it. But I know how you feel. To be honest I would not use it in my track car because 1. I’m a perfectionist....that’s it. (With a healthy dose of anal retentivness) but on a street car where it’s not being pushed to the max.....I think you’d be right. What’s your local machine shop say?

Also I have a mark 1 head here that might have lifters in it. Probably find a few that are just fine you can have

Thanks Glen. I'll clean it up and use it. It's located at the end of the camshaft next to the biggest cap and the seal so it will not affect balance etc. Just disappointing.

If you have a spare lifter you are willing to part with, that would be super. Only 1 out of all of them was spongy, so quite glad there!

Mk1 head flows the best (so they say), do you have one on the race car?
I only talk to the machine shop when I run out of options :D

Hi,

mk2 head flows better.
I have a Japanese service maunal(mk1ph2) indicating that they have enlarged port size from mk1 ph2('87 Oct-).Mk1 ph1 like yours was 97ps but from mk1 ph2, it was 105ps. Or Cultus version in Japan was 115ps.
Keep up the good work.

Cheers
Atchi

Most interesting! Info like that I do not come across often, thanks Atchi.

I will. Looking forward to getting it running with the new cams and a good clean in a couple of weeks!

Pics just for looks. Not a lot of real work done. Too much work, too hot, not enough time and money :D (just normal problems of the car enthusiast)

In a week or so I hope to have this done, lifters done, cams installed and operating. Might need to call in some experienced assistance to double check my work before turning over an interference engine.

Yes, I am going to have to replace that frost plug at some point..... so all of them.... 8-[

Pic shows the hydraulic lifter out of the car (on the left) vs the ones Swift12 sent from a Mk2/3

I don't think it will make a difference, but there is obviously a height difference between the two. Can anyone tell me if there will be trouble?

Also, how the hell do you get these things apart? Would rather reassemble with these things empty.

EDIT: Realised the pic does not show piston height difference that well as I was not low enough, but its there.

Atchi I will be going to Japan later in the year and wondered if there is anywhere over there to buy go fast engine bits?

If only I could afford those elusive "go-fast-bits"! I'm sure there is somewhere to get these from. Oh and, was this the right thread?

I thought I got those out of a mark 1 head michael? I’ll check when I get home but I’m sure they came out of the spare mark one head given to me when I bought the spare car??? I know the spare is a mark 2 but the head is a mark one....has the aluminium fuel rail and a different tps plus a vac dizzy.

Reading back through the thread you do mention a Mk1 head, I must have forgotten at the time I posted, although not sure. Interesting that the lifters are different though. I'll amend the post if they were from a Mk1 head :D
