Step 28 - Now run the belt over the exhaust cam pulley too, tweak the alignment by a tiny amount if required again Step 29 - Check again for deflection, there shouldn't be a lot of play as shown in the picture Step 30 - Ensure the matchmarks for the camp pulleys haven't moved from...

Step 14 - For reference, here's a picture of the routing of the cam belt. It's dead easy, only one adjuster and two cams - count yourself lucky it's not a V8 etc :) Step 15 - Time to get to work on the belt itself, loosen the 14mm nut on the idler pulley and the pulley will release the...

Your cam belt (or timing belt as it is also known) performs an important role - it basically keeps the top end of the engine in synch with the bottom. As the pistons are fired, they translate their movement through the rods to the crankshaft which rotates 2 complete revolutions for a combustion...

The 7th generation of the M series engine (7MGE and 7MGTE) had cooling system issues, head gaskets are common on these but they are otherwise tough and very capable. According to Arnout's site : The MA70 chassis for the NA was supposed to go to the MA71 apparently for the turbo but only few...

This is by no means comprehensive in that there are various options for each car but should give an overview of the various different models of mk3 Supra. The Supra started off life as the Celica-Supra but by the time we reach the mk3, Supra was independent of the roots with Celica. "Supra"...

Separating the box - this is for the auto only : Step 32 - Disconnect all the 17mm nuts and 10mm brackets holding the transmission fluid lines on Step 33 - Now remove all the bolts holding the bellhousing to the engine. Obviously support both ends appropriately because they...

Step 23 - If you have a manual transmission then remove the centre consoler and the gearstick. For an auto you can just disconnect the 10mm bolt where the linkage joins the shifter directly underneath the gearsitck (see picture). For a manual you will need to remove the clutch slave cylinder and...

Step 10 - Remove the throttle cable(s) or bracket (I'd recommend the 14mm bolts on the bracket and then just putting it to one side with the cables attached. Step 11 - Jack the car up so you can start work underneath, ensure you've got axle stands as a back up Step 12 - Looking at...

Step 3 - If your car is fitted with the plastic undertray, undo all the retainers and remove this. Our car wasn't so no pictures Step 4 - You won't be needing electrics any more so disconnect the battery, ensure all windows are up etc because you won't be able to move them without power. 10mm...

I'm afraid this guide wasn't quite as methodical as the normal ones but hopefully it covers most of everything you need. If anyone has anything to add please let me know When removing (and especially refitting) an engine, it's always worth having as many people as you can on hand. At least...

Lubrication of the connecting rods around the crank is achieved via oil passageways that are drilled in the crank, rods and bearings. Oil is fed under pressure into the big end of the rod to lubricate the bearings and provide a surface between the rod/crank/shells to reduce friction and wear...

This part is obviously subject to some serious stresses and special ‘bosses’ are machined into the piston where the gudgeon pin is fitted. There are two main types of gudgeon pin design that are used, these are : 1. The fully floating type (as used in the Supra) where the pin can...

The piston rings sit in ‘ring grooves’ which are separated by the ‘ring lands’ on the piston. These grooves are accurately machined ‘cut outs’ in the piston as shown below The ring grooves have a depth which is slightly larger than the size of the...

In a 4 stroke engine the piston will : a) Move down the chamber/cylinder/hole in the block during the intake stroke where it creates a vacuum and sucks in fresh charge (air) b) When it reaches the bottom (known as ‘Bottom Dead Centre’ or BDC),the piston will momentarily stop and...

This is a different guide to the normal ones – it’s basically a tutorial on rods and pistons, what they do and various factors surrounding them. It is based on a 7MGTE rod and piston but the principle’s the same for most vehicles. As always, feel free to add comments/suggestions. The...

You've got Medallion Man to thank for this one. He did all the leg work, I'm just putting it in the usual format. Step 1 - Get yourself some tools - workbench, saw (or panel saw, the smaller the more precise), pliers, file and some fine sand/glass paper Step 2 - Place the indicator in...

Step 11 - Remove the coolant overflow reservoir, this pulls up although will give quite a bit of resistance until you graze your knuckles. Second picture shows the slidy bit Step 12 - Looking down from above the engine, remove the right hand bracket's two 10mm bolts Step 13 -...
