Skoda Octavia Engine Repair Report

Hello my friend. I am glad to see you on the website newkidscar.com. You see the detail report how to repair engine of the Skoda Octavia Tour DIY below.  The first that I need to do – is diagnose engine problems.

Diagnose engine problems

The Skoda Octavia Tour has equipped the 16-valves 1.4 engine with 75 horsepower. Many drivers mark that German cars are reliable, that is a reason many German cars with big runs.

Our car has driven nearly 300 thousand kilometers before the first engine repair. I drew attention to the timing belt, which had replaced, when the odometer showed 170 thousand km., as evidenced by a special sticker.

All engine`s problems started when the timing belt is broken. Inspection of the belt showed that it operated from 30 to 40 thousand km. The timing belt breaks leads to bent valves on these engines. So I remove the head of the engine block to check this version.

If you have videoscope, you can use it to see traces of valves on the pistons before engine head removing. Such method named videoscope inspection.

Second sign for the engine repair is the flashing oil pressure lamp, that indicates serious problems. Skoda Octavia motors very often require a camshaft bed repair.

Check the camshaft jamming

What is the reason? Clogging oil receiver leads to jamming of one of the camshafts. To check the camshaft jamming: remove the belts (trim them), then scroll the exhaust and intake shaft. In this case, the exhaust shaft is spinning, and the intake shaft is jammed 3.

Removing Engine Head and Checking Valves

Now, I am removing an engine head, check the valves and replace the bent valves on the new. At the same time, I will repair the camshaft beds. It’s good that I remembered to remove the sump and check the condition of the oil receiver.


“It should be noted that the Skoda 1.4 engine often needs repair than the Skoda 1.6 engine.”

When I disassembled the camshaft bed, the head is visible, the bed is separate relative to the head, and the camshafts are inserted on the side. The inlet shaft of the last neck is jammed. I can’t knock it out, so I squeezes it out by the press. I see that pulley has a defect on the protrusion. You see that the shaft turned inside the seat and broke off the ledge 6.

I look at the condition of the camshaft, because jamming it can lead to various other defects, up to breaking the front camshaft toe. Then welding and grinding will have definitely not be avoided. Here`s lucky.

I check the bent valves and then remove the head. I remove the rocker and check that all inlet and outlet valves are in a row. If any valve are lower than the neighboring ones is a sign that the valve caps are bent and the valve cannot close completely. Therefore, I have to remove the engine head and replace the bent valves. I see that my assumptions are true and two inlet valves are bent.

The remaining valves do not have traces of contact with the piston; therefore, they do not require replacement.

All of the pistons, except for one in good condition. But, one piston got such marks from the valves.

There are no backlashes at TDC. The cylinders are also in good condition, even the Hon grid is visible.

As you see engine repair  is not light work because you need looking the defects on the all details. Each small details can be very important to normal engine work.  Sometimes it is important to replace the timing belt in time, so that later you do not have to carry out so many related operations of engine repair.
