You and me both! *laughs*.

T-series, as K-series and many other 'modern' engines, have hydraulic tappets which pressurise when the engine is running to operate the engine's inlet and exhaust valves with the correct clearance. If the engine is left for a while the oil can bleed back out of them, messing up all the clearances and making it run so badly, initially. It 'got better' as they were refilled with oil.

The 'old' way was to have adjustable tappet clearances, either with a screw or shims. The Honda D-series is the latter design.

That makes sense now John!

The finish of the exhaust manifold had started to annoy me, so I thought I'd see what I could do. This is before:-



And this after. It was done in-situ but would be much easier to do it off the car



I used Rust-Oleum Heat Resistant 750°C Black Spray Paint BBQ Exhaust Top Hat.

Let's see how long it lasts...

Probably depends on how hard you drive *laughs*.

With help from Chris Taylor and Richard Jessett, I assembled the 3 parts of the battery tray to replace the one fabricated by Craig during the rebuild so last week I did the swap and while at it, removed repainted and replaced the ABS modulator bracket and tidied up a couple of hoses.

This is where it started



It was a bit of a wiggle to get the modulator bracket out with the modulator still in place but it is possible. Just remember to support the modulator so as not to stress the brake pipes



Then it was a case of assembling the 3-piece battery tray.



I've realised that my battery doesn't fully fill the tray but as I'm unlikely to be doing too many sub-zero starts, it'll cope for the time being

Staying with brakes, my ABS warning light has been on intermittently for some time and as the MOT getting closer, I thought it a good idea to get it sorted, especially as it was getting more to be intermittently off...

Using the fault code access method of grounding the Y/G wire in the under-seat connector and reading the flash code when the ignition is switched on, I got code 47. This was most amusing as the Rover workshop manual lists both 46 and 48 but not 47

Luckily, t'internet provided codes for another vehicle with the Bosch 2S system, the Alfa Romeo 145




So the RHR sensor was the culprit!

Getting the old sensor off was a little awkward, with one fixing shearing and the sensor not wanting to come out of the adaptor. This is indicative of the usual failure mode - over time the nylon sensor head naturally absorbs water and expands inside the aluminium adaptor bore. This swelling causes cracks in the nylon letting in water and the end comes soon. Well, after nearly 30 years! Luckily new adaptors are still available from Motaclan.





The new one went in easily




And the light stays off once the ignition cycle check is completed



NB. Ebay showed many LHR sensors available but all RHR were very expensive. As the rear sensor cable lengths are the same and the fixing is inline with the head, it is possible to convert a LHR into a RHR by carefully prising off the old cable guides and putting them onto the new one

Nice one I've just rebuilt a set of turbo arms and I interested in the ABS bracket you got was it ally as originally or plastic as the later ones ?they are the same dimensionally by the way .

Original aluminium ones which, surprisingly, are still available from Motaclan
