Loosing a lot of oil.

[m1tch]

****UPDATE****

I have changed the gasket and o ring in the chain tensioner and i notice alot of oil all down the right hand side of the engine.....

Also how do you access the crank shaft pulley to get the tensioner to "click" my ratchets are all to wide?

Thanks

Think I managed to get to the nut at the end using one of the swan neck spanners, doesn't need much.

[jonbill]

you can put it in gear and rock it.

[almitch1]

Right,

So the cam cover gasket and the chain tesioner O ring have been changed the engine has been cleaned up a little.

I got her warm..... No oil coming from the gasket or o ring.

Went for a 30 min drive and still all dry...


let hope thats it sorted. I will need to take the under tray off at some point and give it a good clean as it covered in oil and grime.

As i have never done more than change a wheel before im quite chuffed that this week i have changed front discs and pads and now the gasket and O ring.... For most of you its nothing i know but we have all got to start somewhere.

Its thanks to you guys in here, lots of help and guidance...

Thanks

Replace the pcv valve with a new one.

Not a maintenance part but they do go ´off´ over time and are a source for oil loss.

Good result Al. I'm in the same boat as you. Little previous experience of car maintenance or repairs but willing to give it a go, particularly with such a supportive club as this

You're a natural!  We'll have you doing engine rebuilds in no time.

Keep an eye on that oil level.

[almitch1]

I'm not sure about that.. but you never know.

Well done.

Fingers crossed that it was as simple as that.

Doom and gloom postponed until further notice

Top job, stand back and admire your handy work. Hopefully you can move on to sorting out the handling and start enjoying the MR2.

[almitch1]

This was the under tray when I took it out today. Quite clear it was a leak on the right side and has never been attended to.

Let's hope it's all sorted now? All bits down the right side of the engine are covered am I ok to use an engine degreaser all over pulleys and all??

[Carolyn]

I spray them down with plenty of petrol!!  I hook a spray bottle up to our compressor and blast it off.

Best to do it with nappy still off and plenty of carboard under the car.

What about a shop bought engine degreaser?

@almitch1 asked:  am I ok to use an engine degreaser all over pulleys and all??

I would be very careful about what I used to clean around the pulleys, remember there is a rubber belt wrapped around them.

PS
While you are looking around that area may be worthwhile checking the condition of the auxiliary belt. They are a service replacement item. I found I needed an extra hand to change mine but @Carolyn has a workaround to do it with just two.
Be aware that there are two belt lengths available. The shorter one is for cars without air con and the longer is for cars with aircon.
If the belt is off while you are cleaning that is one thing less to worry about.
If you do decide to remove the belt first make a sketch of how the belt goes around the pullies, or maybe in these modern times a photo on your phone, maybe you have one that bounces if you drop it.

Hello all,

Update time. So its been 100miles since i thought i sorted the oil leak. The good news is that the o ring and gasket i replaced are all good. However there seems to be alot of oil on the underneath of the car to the right (as you look from behind) of the sump and filter. Also according to the dipstick its lost nearly half the oil i put in 100 miles ago... Im not sure i took a correct reading but it was startled.

Any ideas?

The crankshaft seal on the pulley?

[Carolyn]

To find the source of the leak, you need to clean off all the muck.  It's a pain. Brush it with grease solvent (petrol is good), then something like brake cleaner, and keep going until you can see what's under there.  Old clothes, beanie and loads of rags needed!

It could be a few things -but that rate of loss would make me want to check for pin holes in the sump.

It could be the front or back crank seals, it could be....O ring on a sensor?? 

Once it's clean, run it a bit and have a look.  It should be more obvious.

The friendly version of gunk.

Clean then observe

Indeed; degreaser, pressure hose, repeat if needed.
