Having issues with my rb25det series 2, on cold starts it knocks. This is after just recently doing the timing belt. How can I check that the timing is 100% correct?

I have also found the previous owner has drilled a 10 cent size hole in the firewall to run his gauges. Can I put a grommet in to protect the wires from rubbing?

What is my best option? I don't want to swap in another rooted engine.

Thanks.

What kind of knock? Detonation or bearing knock? 

Um you check the timing with a timing light. See one of the tutorials on cambelt fitting if you are not sure how.

Why would you not put a grommet in the hole?

You need to take the AC/Alternator belts off then the harmonic balancer then you can check if your timing belt is lined up properly -as Kiwi stated see a tutorial.

Alternatively  you could remove the CAS and top cover only and check that the top marks and the timing mark on the balancer line up, but thats a quick and dirty.  If you did your own belt then you would know this.  If you didn't then its not a place to start learning mekanikin'.  Get a mate who knows to coach you???

The actual electrical timing for firing up a motor is done with a timing light and checking that the light strobes the marks on the balancer pulley line up.

The grommet - you would leak water on a rainy day if you don't have one.  Either slit one and press it in with the wires in place [as a temporary fix], take the wires out and install a grommet and then thread the wires back in [proper way], or if your a meathead get a big silastic gun and bog it up!!!!

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
