Mitsubishi Colt 1.5 4A91 Flywheel Oil Seal

Mitsubishi 4A90, 4A91 and 4A92 engine which is found in newer version of Colt, Lancer or even ASX, should be consider under the same family of engine, their flywheel oil seal (some call it as crankshaft oil seal) is come with the metal housing, initially I thought it should be sharing the same type of oil seal, until I found one of the full set gasket we sold to customer, the customer coming back with their oil seal which they stated the oil seal in the set have slightly different from the one dismantled from engine.

The photo above showing the front side of the oil seal and the photo below is showing the reverse side, the one on top of the photo is the oil seal dismantle out from the engine while the bottom one is the oil seal content in the gasket kit.

At a glance it seems nothing different but one or two screw hole alignment are not in the same place for both oil seal, the oil seal content in the gasket is with the part number 1052A150 or 1052B059, still trying to getting the part number for the oil seal that is taken out from this engine, suspected we may search it under Smart Fortwo or Smart Forfour engine version.

Honda R18A and R20A Overhaul Set Gasket

Below article source are from Wikipedia.

The Honda R engine is an inline-four engine launched in 2006 for the Honda Civic (non-Si). It is fuel injected, has an aluminum-alloy cylinder block and cylinder head, is a SOHC 16-valve design (four valves per cylinder) and utilizes Honda's i-VTEC system. The R series engine has acompression ratio of 10.5:1, features a "drive by wire" throttle system which is computer controlled to reduce pumping losses and create a smooth torque curve.

The engine uses many advanced technologies to improve fuel economy and reduce friction. Piston rings are given an ion plating and weight is reduced with plastic and aluminum parts and variable length intake manifolds that maintain ram air at a wide RPM range. The engine also features piston cooling jets, previously available only on high performance engines, and in the ninth-generation 1.8L Civic (2012-2015) the pistons are treated with molybdenum disulfide applied in a polka-dot pattern. The automatic transmission model is rated at California Air Resources Board (CARB) ULEV-2 (Ultra Low Emissions Vehicle) with fuel economy 25 mpg_‑US (9.4 L/100 km; 30 mpg_‑imp) city, and 36 mpg_‑US(6.5 L/100 km; 43 mpg_‑imp) highway. It also uses the same computer (engine control unit) controlled distributorless coil-on-plug ignition as the Honda K-series engines.

Toyota Corolla TA64 3TG Gasket

Never thought that we will order the Toyota 3TG gasket, we already order the Toyota 18RG and 2TG gasket before that and feel that it may be risky to end up stocking it as all this are under Toyota Classic model that we don't know which day the demand may just stop.

Found the turbocharger gasket in the 3TG overhaul gasket kit which have Japanese wording printed on it.

The 3TG Rocker Cover Gasket set is also a classic design.

This shipment also have the Toyota 18RG Full Set Gasket kit in it.

Finally I can take a family photo for this 3 Toyota classic model gasket kit, from left, is 2TG, 3TG and 18RG.
