Daihatsu Hijet servicing info etc

Jul 26, 2006 7 Replies

Hi - can anyone help with several minor things on a 1997 Daihatsu Hijet van with the 993cc engine.


  1. I recently changed the oil and filter, using 15w40 semi-synthetic. Could be my imagination but since then when starting from cold it seems to take a second or so to get to full oil pressure, and can hear things knocking slightly inside the engine. It's probably fairly normal but comments appreciated. Could there be a non-return valve inside the filter that's faulty? It's hard also to tell the correct level of oil, as the dipstick comes out covered in oil from touching the side of the tube it sits in after taking out, wiping and reinserting, so have put in slightly more than the 3.1 litres recommended in the owners handbook.


  1. I need to know the correct size of socket to get the plugs out. They are pretty much hidden away below the side of the engine, and don't want to damage them as it's difficult to feel if the socket I have is fitting properly. Plugs should be RN9YC NGK.

  2. The ignition setting is stated as 5 deg BTDC, but I cannot find any timing marks on the engine or pulleys - can anyone help me identify them? A connector also apparently needs to be shorted out when checking the timing. I feel it needs checking as the engine is pinking slightly under load when climbing gradients.

Where did you buy the filter from?

NGK's website lists BPR5EY for your vehicle. Look at one in Halfrauds, then buy the correct socket.

Is our pinking expert still around???

Normal for most cars. If you let the car sit for a couple hours, you should get an accurate reading from the dopstick.

Most likely need a 16mm deep socket, or the equivalent spark plug socket (possibly a 12mm). I always use deep sockets now (ie without the rubber insert), as it's easier to tell if the socket is indeed on the plug or not (rather than wondering if it's just the rubber that's gripped)

It's electronic. There's nothing that can be adjusted.

Thanks for reply. Filter was bought from EBC in Hove, can't remember brand but have used their parts before on other vehicles no prob. Can't see the filter on these without removing floor section so difficult to do quick check.

Got plugs out - seemed ok, thin patchy black carbon deposit (not oily) on them, so maybe some carbon in engine causing pinking when hot? Think would help to put injector cleaner in tank but not got a lot of faith these actually do anything.

Thanks for reply. I take your point about it being electronic and should not need adjustment, but it's odd that the setting is shown on a sticker on the passenger door along with some other servicing info if that isn't the case?

The reason I asked is that many oil filters need a non-return valve in them to prevent them draining when the engine stops. Many non-OEM ones omit them, with the result that when starting from cold, it takes longer for the oil pressure to rise.

On the assumption that injector cleaner *may* clean injectors, I'm not sure it will help with carbon deposits in the engine.

Has the vehicle done lots of short, low speed trips? It may just need a long run at whatever qualifies as high speed!

HTH

I thought something like that might be the case. I guess changing the filter again without draining engine oil isn't an option, though the filter is pretty much on the top of the engine? If I knew I could change it again without changing the whole lot would probably do that.

The vehicle has mostly done medium length trips - 45 miles or so, country roads, not many short trips. But I have only driven it for last

4000 miles or so (now showing 55k).

The idea of using the injector cleaner was on the assumption that although it has had regular servicing prior to my using it, an injector cleaner might not have been used to clean them. If the injectors are in any way clogged or dirty, I imagine this might affect combustion or mixture, hence slight sooty deposits on plugs.

Next time I change a filter will go for good quality.

No problem to change the filter on its own.

Makes sense :-)
