Assembly – Timing Cover and Oil Pan

mz12gt — Sat, 10 Dec 2011 01:18:15 +0000

Front Timing Cover Attached

On the 3rd attempt I managed to install the front timing cover with new oil seals. Using the FEL-PRO TCS455181 Kit and 7MGE crankshaft oil seal. I used Hylomar on the gaskets. It’s fiddly stuff but is supposed to work well.

Oil Pan Installed

Installed the new oil-pan I had got from Toyota Part in MI, using the Toyota Black FIPG sealant. Here is hoping it keeps the oil in.

Block – Assembly

mz12gt — Sat, 15 Oct 2011 11:13:39 +0000

So today I attempted for the second time to assemble the engine block. The first time I tried I broke a piston ring meaning that I had to order a whole new set of the things. The 2 most important things when doing an engine assembly are cleaning (mostly with kerosene) and lubrication.

Lubricants

For engine assembly lube I am using Torco MPZ and CRC Sta Lube. For anything that needs oiling I am using Penrite HPR 50 Mineral Oil. And for seating seals I am using Valplex MP Grease.

Cleaned Piston Rings and Bearings

Here are the NPR Piston Rings and Clevite Bearings after they were thoroughly cleaned in Kerosene and then dried off.

Assembled Pistons

Here are my assembled pistons before they are lubed and inserted into the block

And here is the end result.

Cam Covers – Painted

Painted Cam Covers

This is the initial result of painting the cam covers. It will need a little touch up to be perfect. First I cleaned the covers with a wire brush and then sanded them down. Then I prep-washed with 3M Wax and Grease Remover. Then I did an under coat of 3M Engine Enamel in Aluminium Colour. Then masked the Toyota and DOHC signs off and painted it in VHT Wrinkle Plus Black. Waited 48 hours and then baked them in a makeshift oven, made of a heat gun and a fruit box.

6MGE Crank Pulley / Harmonic Balancer – Rebuilt

Sent my harmonic balancer to Precision Parts in Wagga Wagga and they rebuilt it for me. Originally it wasn’t looking so great.

6MGE Crank Pulley / Harmonic Balancer

6MGE Harmonic Balancer

6MGE Harmonic Balancer Chip

The Achilles heel of the 6MGE motor is its harmonic balancer / crank pulley which is prone to chipping.
