Replacing Toyota 2ZZ-GE VVTL-I camshaft lift bolts at 105k miles…

Firstly I’d like to thank the following two guide links, which give you all the information you need for this task:

Targa90’s 7th Generation Celica Lift Bolt Replacement Tutorial

Despite the simplicity of this task I was dreading it a little, it was a must do job but I had no idea if these bolts had been replaced on my car or not.

Judging from my engine and how it looked I assumed not, everything is rather dusty in my engine bay but very undisturbed. Going by all the previous MOT and service history it’s been a very reliable motor and well looked after so I wasn’t expecting problems…

Two things I would advise you get for this task is a 5-25NM torque wrench and a cover sealant, since there are two points on the cover that need cleaning off and new sealant applied to on refitting the cam cover (see Targa90’s link for this).

The cover needed some gentle persuasion to come off as you can imagine, you will notice it almost refuses to come off over in the right rear corner reason being that there is a vertical oil flow tube and it seals pretty tight. It will seem awkward when refitting the cover as well but just keep an eye on the tube and make sure to seat the cover back on as evenly as possible, the bolts will pull the cover back down snug.

When you get the cover off it might be ideal to wrap up the top of the exposed engine, especially if it’s windy and your engine is flailing bits of dust and dirt. Ideally you should give the coil pack recess and all the top section a hoover off first as the metal can be very fatigued by the elements.

So as you can see I was lucky this time ! These bolts I’ve removed are revised ones but not the final versions, I believe with my car being built in the latter of 2002 it come with these from the factory. As you can see the wear is obvious, very more so on the intake bolt shown closest.

All in this job cost me £30.00 to do, the torque wrench, the two bolts and the sealant. I’m very pleased the bolts were not snapped or that they did snap during removal, as that makes things a lot more stressful !

Have a good day everyone.

East Kent College: April Break Post

IMG_2094

The year seems to be going super fast, and finally the weather in the UK is getting better. I’ve mainly been out cycling which has felt somewhat beneficial, and over the break we had an awesome trip at the Go Ape course near Leeds Castle. I’ll be honest I was a little nervous at first since I had no real idea what to do, but after working out the equipment it was really amazing. I want to do a similar course perhaps bigger and more dangerous, probably have to go half way round the world for that !

Here is one of the Folkestone students that was in my group, the zip lines are pretty big, around 250m long and guessing probably around 100ft high.

I tried to use my camera on the big zip line and get a 1/15th shot to show the speed of motion, but I Kinda ended up in a spin… I was holding the cam with two hands and using the viewfinder when I’m supposed to be holding onto the safety harness ! Why did I not use live view you might well ask ? I use the view finder so damn much I forgot about it to be honest. Basically it didn’t work out but I still like the effect…

Like I said with cycling I’ve been doing a lot of that, and the Hope Pro 2 hub I’ve fitted to the bike has really improved the drive pickup, though I’m still getting used to the sound ! Here I’ve parked up at Sandy Lanes just checking it out, a couple of bricks and sticks to move otherwise some of trails seem okay. I want to rebuild the front wheel as well now it seems too weak in comparison. After 16 years I decided to renew the bottom bracket also, it didn’t need one but they are not expensive so I’ve fitted an UN55 in place of the UN52 and it seems good.

In the workshop I’ve completed a few more tasks and only have one left to do now ! Recent ones have been diagnosing a turbo charger pressure fault, audio equipment fault, and a steering related fault. I got to do some kind of pre-MOT inspection so I’m not sure when that is happening because it will have to be done in the other workshop, using the necessary testing facilities like the brake roller.

Here is an example of the evidence I have to submit with diagnosing audio equipment. Although the problem was damage to the component speaker wiring in the door I still have to show a methodical approach, so going to the stereo fuse first, then moving on to checking the output from the head unit amplifier etc. until getting to the component speaker in the door and no signal after entering the door indicates a wiring damage/high resistance.

I got my LV07 assignment passed a few weeks back which is good. This assignment is about describing an electronic fuel injection system and outlining an in depth diagnosis of a specific problem that can occur on the system. I did my investigation about solder breaks on the PCB for a Fuel Pump Relay. I have Mark Lamond with his great website to thank for the in depth look at the Honda CRX.

Main Relay Fault Honda CRX – For LV07

With this I was able to base my own essay off the scenario and pin it onto a newer vehicle. This fault is only common on 80’s / 90’s era cars but it still poses some relativity with vehicles that often cross climates from cold winters to hot summers.

LV07 engine and LV08 chassis exams have both been passed first time as usual. I was not totally impressed with the  engine LV07 exam, getting questions about variable valve timing and just generally old stuff really. There was nothing on electric cars, hybrids, common rail diesel, direct injection, variable turbo geometry etc… I was not really expecting these things to come up, but I think the exams should focus on much newer tech because it gets quite boring covering stuff I learned in my first year.

I end the post on a rather tragic note, and that was the team I participated with did not win the skills competition over at the Broadstairs campus, we came second by half a point ! Well done to EKC Broadstairs for getting 1st place and to the other colleges that took part in the event, it was a good laugh and I leaned a fair bit on the day.
