I have a 1998 freelander 1.8 petrol high milage 149k split mint condition and mechanicly sound all serviced up, iv just changed the oil and filter and put castrol gtx 15/40 grade oil in it, is this the best option oil for my car or sould i be using a different grade oil, any help or advise would be appreciated, kind regards, carl

Hi Jason sorry but the information you have supplied gives me very little to go on. Has this issue just appeared? (1) check oil level correct if low (2) does the oil run off the dipstick or drip off when removed.If it runs off it may require an oil change.If the kilometers are really high use a thicker grade oil.15/40 fit new oil filter. Check if oil is contaminated, if water oil filler and oil will look creamy. If fuel you will smell petrol in oil. Both these issues require fixing 1st before an oil change. It may be an engine fault if all the above is ok and will require a mechanical repair by a mechanic.

2001 2003 LAND ROVER FREELANDER SERVICE MANUAL
just download the service manual and all your queries will be solved :)

Toyota recommend a belt change at 100.000klms (75.000miles) under normal driving conditions Less if constant high speed is the normal drive cycle. I recommend that when changing the belt that all oil seals be replaced along with all idler pulleys and hydraulic adjusters. The reason is simple --Oil is the biggest destroyer of belts and any oil leaks or potential oil leaks are best fixed when the belt is off. Pulley bearings are at their useful life when the belt is due for a change so replacing them and the oil seals means another full period of service.l

Have an oil pressure test done. That requires a mechanical oil pressure gauge attached to engine. These are notorious for oil pump wearing out due to improper oil change techniques. Attached is note from Rover service manual;

Oil filter renewal

NOTE: To avoid draining the oil pump, it is essential that the engine is filled with oil to the correct level, before the filter is removed. It is therefore recommended that the engine oil is renewed before work on the filter commences.

if it sounds ok then leave it alone ,change oil every 6000m and oil filter every third oil change and use the cheapest oil for a diesel/petrol you can find so engine stays clean and it will last forever ,cruise ?well this could be anything so ask a local mechanic to have a look for you ,as for the phone well sometimes your better off without the thing .

on the inlet manifold is a breather from the engine i think on this year so check for a split vacumn hose or a split breather pipe ,failing which it could be the thingy on the back end of the butterfly ,their is a sensor but iam pretty sure its a breather pipe or something stupid ,also pull the vac pipe out of the servo and just try pùtting a plug into pipe in case the servo diaphram has split

CHANGE THE OIL TO TOP QUALITY OIL THEN CHANGE THE SPARK PLUGS TO BETTER SPARK MOST PROBABLY IRIDIUM THEN CHANGE THE AIR FILTER TO A BMG AIR FILTER (THIS AIR FILTER DOESNT EVER NEED CHANGING) THEN FILL THE PETROL (IF IT NOT DIESEL) WITH HIGH OCTANE (98ron) AND ADD RACING OCTANE BOOST TO THE PETROL TANK AND THAT WILL SOLVE THE PROBLEM AND YOUR CAR WILL GO A HELL OF ALOT BETTER YOULL SAVE ON FUEL ALSO THE IRIDIUM SPARK PLUGS DONT HAVE TO BE CHANGED FOR AT LEAST 100.000KLM HOPFULLY THE PETROL AND MORE AIR GOING IN WILL HELP

True that kind of problem must diagnostic the ecu in order to know further more where the problem come from,hope that clear your mind man,

Lefthand side of the engine compartment bulkhead, if its a diesel, beneath the rear seat, (fold down), remove inspection panel, and remove pump, filter is inside, for petrol.

Look in the owners manual it should give you a time line or at about 60k
