560SEL EHA replacement 2

560SEL EHA replacement

Today’s job was EHA replacement (Electro-Hydraulic Actuator) on my 1987 560SEL.   The EHA is part of the KE Jetronic fuel injection system and makes minute adjustments to the air/fuel mixture.   One of the sources for these adjustment is the oxygen sensor, if present.   The EHA can leak either because the o-rings between the EHA and the fuel distributor have gone hard, or because of...

November 2020 Night drive to Bilpin 2

November 2020 Night drive to Bilpin

The monthly late night drives are really starting to gain momentum.   This month was a bit different.  It started out as a Night drive to Bilpin.   As well as a drive, we had late night dessert and coffee.   Summer in Sydney is a great time for night drives.  The weather is pleasant and its a great time for convertibles or sunroofs to be open....

W126 battery tray 2

W126 battery tray

The W126 battery tray serves a dual purpose.   The first and most obvious is to keep the battery in place.  The other is to protect the body work.  Over time car batteries can leak acid and the removable tray catches all that.    It is worth checking the condition of the battery tray each time the battery is replaced.   If the battery tray becomes...

300SE low oil pressure gauge 5

300SE low oil pressure gauge

Today I took my 300SE on a Mercedes Club Pop up drive.   The Pop up drives are short notice mid-week drives.  I normally take the other cars to club events, but the 300SE had not been on a decent run for a while and the weather was terrible.   The drive was down through the Royal National park to Mt Kembla, Mt Kiera and then...

Youngtimer Sacco Day 2020 2

Youngtimer Sacco Day 2020

The Mercedes Benz club NSW ran an event today to commemorate the cars of Bruno Sacco.   Sacco was head of design at Mercedes-Benz from 1975-1999.    The event was called Youngtimer Sacco day and I understand the intention is to make it an annual event.   Given the success of today’s event, I can easily see why. The event started out at Tynan’s Mercedes-Benz dealership...

250SE extended test drive 0

250SE extended test drive

After all the recent work done on my 250SE, I wanted to take it for an extended test drive.   Its had motor and transmission mounts, front crank seal, re-sealed power steering pump, injectors, distributor cap and rotor, points, condenser, coil, plugs, alternator, voltage regulator and more done.     The spark had been quite weak and the engine was carboned up. The Mercedes-Benz club have...

250SE Alternator replacement 2

250SE Alternator replacement

On the way back from the September night drive my 250SE stopped charging properly.   I was able to make it back home about an hour on the battery.   Even using the headlights the 250SE does not use a lot of power.   As it happened, a friend of mine had a rebuilt alternator that was correct for my car.   He drives a 280SE 3.5 W108...

M129 rough running 1

M129 rough running

Over the last couple of months I’ve had issues with the M129 rough running in my 250SE.   The car was hesitating, idling poorly and just not running very well.   I’ve done a few things over the last few months to improve this situation. One of the first things I did was change the injectors.   The stutter when accelerating and hard starting when hot felt...

Fuel leak damage repaired 3

Fuel leak damage repaired

I recently changed the fuel pump and rear fuel hoses on my Jaguar E-Type.   In doing this change I learned a few things.   Firstly, the old pump had not been delivering enough fuel, as the car was significantly more responsive.   Secondly, fuel had obviously been leaking for a while as the paint had been eaten away in the spare tyre well. For both these...

MBCNSW Dam Drive 0

MBCNSW Dam Drive

Today I went on a drive with the MBCNSW to visit some historic dams to the South of Sydney.  The idea was to supposed to be to go to each dam and check it out and then have a picnic lunch at one of them.   Unfortunately the Sydney weather did not play ball and it was a rather wet and wild day.   I brought...
