I had one a few years back, was cracking, there a great drive. Even the standard engine is enough for a good giggle. I had the precats cut out of mine, mine used plenty of oil mind.

They got some good praise when then came out, was funny I was just watching a vid this morning, one with a Honda k20 in.

Might take the mr2 to work tomorrow. It'd be terrible* if I blew the engine and we had to do the 2zz conversion sooner...

Makes a change from the Locost, at least this has a heater. And a roof. Note a bad commute despite it being sub zero out...

My prediction is it'll be fine the rod through the block on that S bend at the end of the straight at Knockhill

I estimate this car needs £3000 maybe £4000 spending on it to get it rite and when this is done it will be wotrth about £1500!!

Not broke it yet. I'm thinking the noise is timing chain related so have unplugged the vvti solenoid at lunchtime to see if that does anything on the way home.

So, with the VVTi solenoid unplugged the noise is still there but the characteristics changed.

 

Kind of hard to explain but it makes the noise at a different point in the rev range with it unplugged. So, VVTi solenoid is coming out along with a mesh filter which is located near it, I'm tempted to pull the cam cover off too for a nosey. The history is patchy so god knows when it last had an oil change, I picked up a filter today too.

 

Sadly I'm away with work this weekend so won't get to see it in daylight for nearly 2 weeks.

 

Kicked it's arse a wee bit tonight on the way home, the engine feels pretty healthy. Tyre pressures are all over the place and the roads are damp so I didn't get too exuberant though...

I was about to mention that I hoped you’d let the cabin heat the roof up a bit, prior to dropping it, as it can screw the canvas. Then I remembered that it’s clearly not an issue!! Great to see someone else enjoying a Roadster - they can become quite addictive.

Them yellow cubes from out of a proper old-school urinal are easy to sneak in and a better buzz than any modern chemical shit. Never done me any harm.

Not a lot to report on this front, I was away with work at the weekend so haven't had a chance to do much. 

 

The first parts purchase arrived:

 

c340da4c-8836-4358-a0bc-1722ccdbd6da.jpg

 

A timing chain tensioner and cam cover gasket-the tensioner is a possible issue and the cam cover gasket for when I pull it off for a nosey-the current one leaks

 

I nipped out on my lunchbreak and changed the tensioner but this made no difference-still rattling.

 

Today my mate brought around this

 

IMG_20171115_200020117.jpg

 

We took turns to listen to the engine while the other one made it make the noise-most noticeable on the way up and down the rev range at around 2500-3000RPM.

 

After much revving, no doubt pissing off my neighbours, we came to the following conclusion.

 

It rattles.

 

The precise location of said rattle still eludes us however.

 

A list has been compiled. We intend to spend anything up to £20 on fixing this engine before we give up on it and fit a fast one. £20 being the price of a new set of big end bearings.

Could the camshaft phase varying thing / VVT gadget be the rattle? It looks like the sort of thing that could rattle in that sort of non- descript way.

So the VVTeyes have a solenoid? Mine sounds sweet, but it's never gone wild at higher revs...

Nah, we're not sure. I thought it was coming from the timing chain end but the stethoscope didn't bear this out 100% More investigations will follow

Quite possible but I'm not sure how to test it.

Aye, the solenoid allows oil to flow into the VVTi pulley-the oil locks the pulley into a different position varying the timing. These can fail, they also have a filter I can clean out

Had a day off today so managed to get some car work done.

 

First up, the S4. A rattle over bumps sounded an awful lot like drop links. I bought a set, er, several months ago but had never got round to fitting them. Job done, first rattle gone I then turned my attention to the MR2.

 

I stuck the back end up on a set of ramps with the intention being to check the heat shields on the cat and have a listen to the bottom end using our stethocscope.

 

A mate arrived and I got the MR2 to play it's tune whilst we took turns again to listen. Again, nothing conclusive. 

 

Once under there the sump is just winking at you. Access is great. A plan was formed. Oil was dropped, lunch was eaten (square sausage, of course) and suitably fortified we set out. 

 

Very shortly afterwards the sump was off and numbers 1 and 4 big end bearings were available for perusal. Both had some play in them before unbolting them which indicated we were on the right track.

 

Number 4 looks a bit worn but not too bad.

 

IMG_20171117_162718268.jpg

 

Number 1 however...

 

IMG_20171117_162845578.jpg

 

IMG_20171117_162829543.jpg

 

S'fucked mate.

 

 

You'll note how we go for F1 levels of workplace cleanliness here at Cowboy Motorsport.

 

IMG_20171117_162706842.jpg

 

 

The crank seems OK. I'll inspect it properly and will maybe CAREFULLY smooth it over with emery paper.

 

Likewise the sump contained no nastiness and the oil whilst black looked OK.

 

I phoned my trusted engine rebuilders and have a set of bearings lined up for £40, these are half the price Toyota quoted but twice the price of ebay cheapies-the guy double checked the code against the one I gave him from the old ones so they are correct and we should have them Monday or Tuesday. They are also a decent quality bearing.

 

So, plan is.

 

Check/clean crank.

Fit new bearings.

New Oil filter

Refit sump

Fill with oil.

GLF (a bit)

Then all being well give it another oil change in a couple of hundred miles.

GLF (some more)

Ouch! Be save of the century if you get away with that one. Saying that, I can't say I wouldn't try it myself: what's to lose at that price?

There's a good chance the mains are just as bad, is it worth changing the halves you can get at?

Can you feel anything other than silky smoothness over the crank journals with a finger nail?

Those bearings look wierd too - like they have eroded rather than worn.

This may be a long shot but at the end of the day the 140bhp engines in these are, as we say in the old country, fucking shit.

If this doesn't cure it and get us on the track then it'll get thrown in a skip and the 190bhp engine from a Corolla will get put in!

I reckon this'll have a 190 in it before next summer. If it does, I'm bringing mine up for the same treatment ;)

I've had loads of shells like that.

Over revving, water too hot thus making oil too thin, lack of oil. lack of water.

I've done the crank with emery too. Lasted a full meeting almost.

It'll be reet.

Might last a week. If it lasts a month it will go forever.

Don't travel too far from home.

Reminds me of the 200sx boys dropping the sumps on their 1800 Turbos to do a quick swap of the bearings. That’d be the CA18DET in the s13, obvs.

Funny you should say that, the last time I did this was on the 200sx belonging to my mate who helped me on Friday!
