PCV valve location for 1HD FTE engine (3 Viewers)

[akikan]

Hello Everyone,

I am really new to the LC, recently got my uncle's 2001 LC100 4.2 TD diesel, i am planning to change the timming belt and thermostat, since it stuck open. I also want to replace the PCV valve as well, but could not find where is it? Thank you

I am not exactly sure what you are looking for, as I think you may mean some of the valves in the Exhaust Gas Recirculation (EGR) system -- so may I suggest start by perusing the attached document, especially diagrams and text on the following pages:
p. 139
p. 148
p. 149

Then I would suggest peruse the relevant pages of the Factory Service Manual,

Go to
LC100 Workshop Manual - https://lc100e.github.io/
then use the index panel on the LHS of the opening page and peruse the tabs labelled as follows:

+ Repair Manual
+ Engine Repair Manual [1HZ, 1HD-T, 1HD-FTE]
then under 1HD-FTE, peruse
+ DIAGNOSTICS
+ Engine
+ EGR Control Circuit

Also (under 1HD-FTE)
+ EMISSION CONTROL
+ PARTS LAYOUT AND SCHEMATIC DRAWING
+ LOCATION
+ DRAWING

Also (under 1HD-FTE)
+ POSITIVE CRANKCASE VENTILATION (PCV) SYSTEM
+ INSPECTION

Also (under 1HD-FTE)
+ EXHAUST GAS RECIRCULATION SYSTEM (EGR)
+ COMPONENTS
+ INSPECTION

Also doing a search for "1HD-FTE" threads at the IH8MUD Diesel forum may give more insights:

Diesel Tech / 24 volts

May I also suggest that it is worthwhile to research “catch cans” which can be installed between the crankcase breather and the turbo. The idea is to catch the oil mist and reduce oily, sooty deposits in the turbo, intercooler, intake manifold and intake valves. There is some controversy. There are many supporters. Others say that the additional flow resistance may cause back pressure and lead to excessive crankcase pressure creating other problems. Another view is to disable the EGR system – but that is illegal in most jurisdictions. There are many “catch cans” available – the widely distributed “Provent” series made by Mann + Hummel are well-regarded.

Yea, i was even thinking if we can add oil catch can and keep the EGR at the sametime, since i am in africa, deleting EGR, i guess it's still possible...
